Optional configurations include devices with active-high and active-low output signals (TPS3824/5), devices with a watchdog timer (TPS3820/3/4/8), and devices with manual reset (MR) pins (TPS3820/3/5/8). RESET asserts when the supply voltage, V , rises above 1.1 V. For devices with active-low output logic, the device monitors V and keeps DD DD RESET low as long as V remains below the negative threshold voltage, V . For devices with active-high DD IT− output logic, RESET remains high as long as V remains below V . An internal timer delays the return of the DD IT− output to the inactive state (high) to ensure proper system reset. The delay time, t , starts after V rises above d DD the positive threshold voltage (V + V ). When the supply voltage drops below V , the output becomes IT− HYS IT− active (low) again. All the devices of this family have a fixed-sense threshold voltage, V , set by an internal IT– voltagedivider,sonoexternalcomponentsarerequired. The TPS382x family is designed to monitor supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The devices are available in a 5-pin SOT-23 package and are characterized for operation over a temperature range of −40°C to 85°C. 8.2 Functional Block Diagram V DD + (1) 52 kW _ RESET RESET Logic RESET V REF (2) MR Auto-Reset Oscillator 40 kW (3) Transition Watchdog WDI Detector Timer Logic (1) TPS3824/5 (2) TPS3820/3/5/8 (3) TPS3820/3/4/8 8.3 Feature Description 8.3.1 ManualReset(MR) The MR input allows an external logic signal from processors, logic circuits, and/or discrete sensors to force a reset signal regardless of V with respect to V or the state of the watchdog timer. A low level at MR causes DD IT– theresetsignalstobecomeactive. 8.3.2 Active-HighorActive-LowOutput All TPS382x devices have an active-low logic output (RESET), while the TPS3824/5 devices also include an active-highlogicoutput(RESET). 8.3.3 Push-PullorOpen-DrainOutput AllTPS382xdevices,exceptforTPS3828,havepush-pulloutputs.TPS3828deviceshaveanopen-drainoutput. 10 SubmitDocumentationFeedback Copyright©1998–2018,TexasInstrumentsIncorporated ProductFolderLinks:TPS3820 TPS3823 TPS3824 TPS3825 TPS3828

TPS3820,TPS3823,TPS3823A,TPS3824,TPS3825,TPS3828 www.ti.com SLVS165L–APRIL1998–REVISEDJANUARY2018 Feature Description (continued) 8.3.4 WatchdogTimer(WDI) The TPS3820, TPS3823, TPS3824, and TPS3828 devices have a watchdog timer that must be periodically triggered by either a positive or negative transition at WDI to avoid a reset signal being issued. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, t ,RESET becomes active tout forthetimeperiodt .Thiseventalsoreinitializesthewatchdogtimer. d The watchdog timer can be disabled by disconnecting the WDI pin from the system. If the WDI pin detects that it is in a high-impedance state, the TPS3820, TPS3823, TPS3824, or TPS3828 will generate its own WDI pulse to ensure that RESET does not assert. If this behavior is not desired, place a 1-kΩ resistor from WDI to ground. This resistor will help ensure that the TPS3820, TPS3823, TPS3824, or TPS3828 detects that WDI is not in a high-impedancestate. In applications where the input to the WDI pin is active (transitioning high and low) and the TPS3820, TPS3823, TPS3824, or TPS3828 is asserting RESET, RESET is stuck at a logic low after the input voltage returns above V . If the application requires that input to WDI be active when the reset signal is asserted, then either the A IT– version of the device or a FET should be used to decouple the WDI signal. The A version does not latch the resetsignaltotheassertedstateifaWDIpulseisreceivedwhileRESETisasserted.AnexternalFETdecouples the WDI signal by disconnecting the WDI input when RESET is asserted. For more details on this, see Decoupling WDI During Reset Event. The A version of the device does not require this FET, but it does operate incircuitsthathaveit.Therefore,the Aversionisbackwards-compatiblewiththenon-Aversions. 8.4 Device Functional Modes Table1liststhefunctionalmodesoftheTPS382xdevices.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The TPS382x family of devices are very small supervisory circuits that monitor fixed supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The TPS382x family operates from 1.1 V to 5.5 V. Orderable options include versions with either push-pull or open-drain outputs, versions that use active-high or active-low logic for output signals, versions with a manual reset pin, and versions with a watchdog timer. See the Device Comparison Table for an overviewofdeviceoptions. 9.2 Typical Applications 9.2.1 SupplyRailMonitoringWithWatchdogTime-Outand200-msDelay The TPS3823A can be used to monitor the supply rail for devices such as microcontrollers. The downstream device is enabled by the TPS3823A once the voltage on the supply pin (V ) is above the internal threshold DD voltage (V + V ). The downstream device is disabled by the TPS3823A when V falls below the threshold IT– HYS DD voltage minus the hysteresis voltage (V ). The TPS3823A also issues a reset signal if the WDI input is not IT– periodically triggered by a positive or negative transition at WDI. When the supervising system fails to retrigger thewatchdogcircuitwithinthetime-outinterval,t ,RESETbecomesactiveforthetimeperiodt . tout d Some applications require a shorter reset signal than the 200 ms that most of the TPS382x family provide. In these cases, the TPS3820 is a good choice because it has a delay time of only 25 ms. If an open-drain output is required, replace the TPS3823A with the TPS3828 (if the WDI input must be active while RESET is low, see DecouplingWDIDuringResetEvent ).Figure9 showstheTPS3823Ainatypicalapplication. 3.3 V V 100 nF V DD DD RESET RESET TPS3823A-33 MSP430C325 MR WDI I/O GND GND Figure9.

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
