The charger can be used to charge a battery, power a system or both. The charger has three phases of charging: Pre-charge to recover a fully discharged battery, fast-charge constant current to supply the buck charge safely and voltage regulation to safely reach full capacity. The charger is very flexible, allowing programming of the fast-charge current and Pre- charge/Termination Current. This charger is designed to work with a USB connection or Adaptor (DC out). The chargeralsocheckstoseeifabatteryispresent. The charger also comes with a full set of safety features: JEITA Temperature Standard, Over-Voltage Protection, DPM-IN,SafetyTimers,andISETshortprotection.Allofthesefeaturesandmorearedescribedindetailbelow. The charger is designed for a single power path from the input to the output to charge a single cell Li-Ion or Li- Pol battery pack. Upon application of a 5VDC power source the ISET and OUT short checks are performed to assureaproperchargecycle. If the battery voltage is below the LOWV threshold, the battery is considered discharged and a preconditioning cycle begins. The amount of precharge current can be programmed using the PRE-TERM pin which programs a percentoffastchargecurrent(10to100%)astheprechargecurrent.Thisfeatureisusefulwhenthesystemload isconnectedacrossthebattery“stealing” thebatterycurrent.Theprechargecurrentcanbesethighertoaccount for the system loading while allowing the battery to be properly conditioned. The PRE-TERM pin is a dual function pin which sets the precharge current level and the termination threshold level. The termination "current threshold"isalwayshalfoftheprechargeprogrammedcurrentlevel. Once the battery voltage has charged to the V threshold, fast charge is initiated and the fast charge current LOWV isapplied.ThefastchargeconstantcurrentisprogrammedusingtheISETpin.Theconstantcurrentprovidesthe bulk of the charge. Power dissipation in the IC is greatest in fast charge with a lower battery voltage. If the IC reaches 125°C the IC enters thermal regulation, slows the timer clock by half and reduce the charge current as needed to keep the temperature from rising any further. Figure 14 shows the charging profile with thermal regulation. Typically under normal operating conditions, the IC’s junction temperature is less than 125°C and thermalregulationisnotentered. Once the cell has charged to the regulation voltage the voltage loop takes control and holds the battery at the regulationvoltageuntilthecurrenttaperstotheterminationthreshold.Theterminationcanbedisabledifdesired. The CHG pin is low (LED on) during the first charge cycle only and turns off once the termination threshold is reached,regardlessiftermination,forchargecurrent,isenabledordisabled.

The part is considered “dead” and all the pins are high impedance. Once the IN voltage rises above the UVLO threshold the IC will enterSleepModeorActivemodedependingontheOUTpin(battery)voltage. 9.3.2 UVLO Thebq2409xfamilyisinpowerdownmodeiftheINpinvoltageislessthanV .Thepartisconsidered“dead” UVLO andallthepinsarehighimpedance. 9.3.3 Power-Up The IC is alive after the IN voltage ramps above UVLO (see sleep mode), resets all logic and timers, and starts to perform many of the continuous monitoring routines. Typically the input voltage quickly rises through the UVLO and sleep states where the IC declares power good, starts the qualification charge at 100mA, sets the input current limit threshold base on the ISET2 pin, starts the safety timer and enables the CHG pin. See Figure15. 9.3.4 SleepMode If the IN pin voltage is between than V +V and UVLO, the charge current is disabled, the safety timer OUT DT counting stops (not reset) and the PG and CHG pins are high impedance. As the input voltage rises and the charger exits sleep mode, the PG pin goes low, the safety timer continues to count, charge is enabled and the CHGpinreturnstoitspreviousstate.SeeFigure16. 9.3.5 NewChargeCycle A new charge cycle is started when a good power source is applied, performing a chip disable/enable (TS pin), exiting Termination and Timer Disable Mode (TTDM), detecting a battery insertion or the OUT voltage dropping below the V threshold.

When the input voltage drops to the V threshold the internal pass FET IN-DPM starts to reduce the current until there is no further drop in voltage at the input. This would prevent a source with voltage less than V to power the out pin. This works well with current limited adaptors and USB ports as IN-DPM long as the nominal voltage is above 4.3V and 4.4V respectively. This is an added safety feature that helps protectthesourcefromexcessiveloads. 9.3.11 OUT The Charger’s OUT pin provides current to the battery and to the system, if present. This IC can be used to charge the battery plus power the system, charge just the battery or just power the system (TTDM) assuming the loads do not exceed the available current. The OUT pin is a current limited source and is inherently protected against shorts.

The TS function for bq24090, bq24091 and bq24095 follow the classic temperature range and disable charge when the battery temperature outside of the 0°C and 45°C operating temperature window. The TS function for bq24092 and bq24093 are designed to follow the new JEITA temperature standard for Li-Ion and Li-Pol batteries. There are now four thresholds, 60°C, 45°C, 10°C, and 0°C. Normal operation occurs between 10°C and 45°C. If between 0°C and 10°C the charge current level is cutinhalfandifbetween45°Cand60°Ctheregulationvoltageisreducedto4.1Vmax,seeFigure17. The bq2409x family has devices to monitor 10k and 100k NTC thermistors. The bq24090/2/5 are designed to work with a 10k NTC. For these devices, the TS feature is implemented using an internal 50μA current source to bias the thermistor (designed for use with a 10k NTC β = 3370 (SEMITEC 103AT-2 or Mitsubishi TH05-3H103F) connectedfromtheTSpintoV .Ifthisfeatureisnotneeded,afixed10kcanbeplacedbetweenTSandV to SS SS allow normal operation. This may be done if the host is monitoring the thermistor and then the host would determine when to pull the TS pin low to disable charge. The bq24091/3 are designed to work with a 100k NTC. For these devices, the TS feature is implemented using an internal 5μA current source to bias the thermistor (designed for use with a 100k NTC β = 3370) connected from the TS pin to V . If this feature is not needed, a SS fixed 100k can be placed between TS and V to allow normal operation. This may be done if the host is SS monitoringthethermistorandthenthehostwoulddeterminewhentopulltheTSpinlowtodisablecharge. The TS pin has two additional features, when the TS pin is pulled low or floated/driven high. A low disables charge(similartoahighonthe BAT_EN feature)andahighputsthechargerinTTDM. Above 60°C or below 0°C the charge is disabled. Once the thermistor reaches ≈–10°C the TS current folds back to keep a cold thermistor (between –10°C and –50°C) from placing the IC in the TTDM mode. If the TS pin is pulled low into disable mode, the current is reduced to ≈30μA, see Figure 15. Since the I current is fixed along TS with the temperature thresholds, it is not possible to use thermistor values other than the 10k or 100k (depending ontheIC)NTC(at25°C). 9.4 Device Functional Modes 9.4.1 TerminationandTimerDisableMode(TTDM)-TSPinHigh The battery charger is in TTDM when the TS pin goes high from removing the thermistor (removing battery pack/floatingtheTSpin)orbypullingtheTSpinuptotheTTDMthreshold. When entering TTDM, the 10 hour safety timer is held in reset and termination is disabled. A battery detect routine is run to see if the battery was removed or not. If the battery was removed then the CHG pin will go to its high impedance state if not already there. If a battery is detected the CHG pin does not change states until the current tapers to the termination threshold, where the CHG pin goes to its high impedance state if not already there(theregulatedoutputwillremainon). The charging profile does not change (still has pre-charge, fast-charge constant current and constant voltage modes).Thisimpliesthebatteryisstillchargedsafelyandthecurrentisallowedtotapertozero. When coming out of TTDM, the battery detect routine is run and if a battery is detected, then a new charge cycle beginsandtheCHGLEDturnson. If TTDM is not desired upon removing the battery with the thermistor, one can add a 237k resistor between TS and V to disable TTDM. This keeps the current source from driving the TS pin into TTDM. This creates ≈0.1°C SS errorathotanda≈3°Cerroratcold. 9.4.2 Timers The pre-charge timer is set to 30 minutes. The pre-charge current, can be programmed to off-set any system load,makingsurethatthe30minutesisadequate. The fast charge timer is fixed at 10 hours and can be increased real time by going into thermal regulation, IN- DPM or if in USB current limit. The timer clock slows by a factor of 2, resulting in a clock than counts half as fast wheninthesemodes.Ifeitherthe30minuteortenhourtimertimesout,thechargingisterminatedandthe CHG pingoeshighimpedanceifnotalreadyinthatstate.ThetimerisresetbydisablingtheIC,cyclingpowerorgoing intoandoutofTTDM. 22 SubmitDocumentationFeedback Copyright©2010–2015,TexasInstrumentsIncorporated ProductFolderLinks:bq24091 bq24090bq24092 bq24093 bq24095

If the battery is present, the charge current will terminate. If the battery wasremovedalongwiththethermistor,thentheTSpinisdrivenhighandthechargeentersTTDM.Ifthebattery was removed and the TS pin is held in the active region, then the battery detect routine will continue until a batteryisinserted. 9.4.4 BatteryDetectRoutine The battery detect routine should check for a missing battery while keeping the OUT pin at a useable voltage. WheneverthebatteryismissingtheCHGpinshouldbehighimpedance. The battery detect routine is run when entering and exiting TTDM to verify if battery is present, or run all the time if battery is missing and not in TTDM. On power-up, if battery voltage is greater than V threshold, a battery RCH detectroutineisruntodetermineifabatteryispresent. The battery detect routine is disabled while the IC is in TTDM, or has a TS fault. See Figure 20 for the Battery DetectFlowDiagram. 9.4.5 RefreshThreshold After termination, if the OUT pin voltage drops to V (100mV below regulation) then a new charge is initiated, RCH butthe CHGpinremainsatahighimpedance(off). 9.4.6 StartingaChargeonaFullBattery The termination threshold is raised by ≉14%, for the first minute of a charge cycle so if a full battery is removed and reinserted or a new charge cycle is initiated, that the new charge terminates (less than 1 minute). Batteries that have relaxed many hours may take several minutes to taper to the termination threshold and terminate charge.

This input supply should be well regulated. If located morethanafewinchesfromthebq2409xINandGNDterminals,alargercapacitorisrecommended. 12 Layout 12.1 Layout Guidelines To obtain optimal performance, the decoupling capacitor from IN to GND (thermal pad) and the output filter capacitors from OUT to GND (thermal pad) should be placed as close as possible to the bq2409x, with short tracerunstobothIN,OUTandGND(thermalpad). • All low-current GND connections should be kept separate from the high-current charge or discharge paths from the battery. Use a single-point ground technique incorporating both the small signal ground path and the powergroundpath. • The high current charge paths into IN pin and from the OUT pin must be sized appropriately for the maximum chargecurrentinordertoavoidvoltagedropsinthesetraces • The bq2409x family is packaged in a thermally enhanced MLP package. The package includes a thermal pad to provide an effective thermal contact between the IC and the printed circuit board (PCB); this thermal pad is also the main ground connection for the device. Connect the thermal pad to the PCB ground connection. It is best to use multiple 10mil vias in the power pad of the IC and in close proximity to conduct the heat to the bottomgroundplane.Thebottomgroundplaceshouldavoidtracesthat “cutoff”thethermalpath.Thethinner the PCB the less temperature rise. The EVM PCB has a thickness of 0.031 inches and uses 2 oz. (2.8 mil thick)copperontopandbottom,andisagoodexampleofoptimalthermalperformance. 12.2 Layout Example Figure26.

The package includes a thermal pad to provide an effective thermal contact between the IC and the printed circuit board (PCB). The power pad should be directly connected to the VSS pin. Full PCB design guidelines for this package are provided in the application note entitled: Power Pad Thermally Enhanced Package Note (SLMA002). The most common measure of package thermal performance is thermal impedance (θ ) measured (or modeled) from the chip JA junctiontotheairsurroundingthepackagesurface(ambient).Themathematicalexpressionfor θ is: JA θ =(T –T)/P JA J where • T =chipjunctiontemperature J • T=ambienttemperature • P=devicepowerdissipation (2) (2) Factorsthatcaninfluencethemeasurementandcalculationof θ include: JA • Whetherornotthedeviceisboardmounted • Tracesize,composition,thickness,andgeometry • Orientationofthedevice(horizontalorvertical) • Volumeoftheambientairsurroundingthedeviceundertestandairflow • Whetherothersurfacesareincloseproximitytothedevicebeingtested Due to the charge profile of Li-Ion and Li-Pol batteries the maximum power dissipation is typically seen at the beginningofthechargecyclewhenthebatteryvoltageisatitslowest.Typicallyafterfastchargebeginsthepack voltage increases to ≉3.4V within the first 2 minutes. The thermal time constant of the assembly typically takes a few minutes to heat up so when doing maximum power dissipation calculations, 3.4V is a good minimum voltage to use. This is verified, with the system and a fully discharged battery, by plotting temperature on the bottom of the PCB under the IC (pad should have multiple vias), the charge current and the battery voltage as a function of time.Thefastchargecurrentwillstarttotaperoffifthepartgoesintothermalregulation. The device power dissipation, P, is a function of the charge rate and the voltage drop across the internal PowerFET.Itcanbecalculatedfromthefollowingequationwhenabatterypackisbeingcharged: P=[V –V ]×I +[V –V ]×I (2) (IN) (OUT) (OUT) (OUT) (BAT) (BAT) The thermal loop feature reduces the charge current to limit excessive IC junction temperature. It is recommended that the design not run in thermal regulation for typical operating conditions (nominal input voltage and nominal ambient temperatures) and use the feature for non typical situations such as hot environments or higher than normal input source voltage. With that said, the IC will still perform as described, if the thermal loop isalwaysactive. 12.3.1 LeakageCurrentEffectsonBatteryCapacity Todeterminehowfastaleakagecurrentonthebatterywilldischargethebatteryisaneasycalculation.Thetime from full to discharge can be calculated by dividing the Amp-Hour Capacity of the battery by the leakage current. For a 0.75AHr battery and a 10μA leakage current (750mAHr/0.010mA = 75000 Hours), it would take 75k hours or 8.8 years to discharge.
