TL7702B,TL7705B,TL7733B www.ti.com SLVS037N–SEPTEMBER1989–REVISEDSEPTEMBER2016 8 Detailed Description 8.1 Overview The TL7702B, TL7705B, and TL7733B are integrated-circuit supply-voltage supervisors designed for use as reset controllers in microcomputer and microprocessor systems. The supply-voltage supervisor monitors the supply for undervoltage conditions at the SENSE input. During power up, the RESET output becomes active (low) when V attains a value approaching 1 V. As V approaches 3 V (assuming that SENSE is above V ), CC CC T+ thedelay-timerfunctionactivatesatimedelay,afterwhichoutputs RESETandRESETgoinactive(highandlow, respectively). When an undervoltage condition occurs during normal operation, outputs RESET and RESET go active. To ensure that a complete reset occurs, the reset outputs remain active for a time delay after the voltage at the SENSE input exceeds the positive-going threshold value. The time delay is determined by the value of the externalcapacitorC :t ≈2.6 × 104×C ,whereC isinfarads(F)andt isinseconds(s).

The external capacitor charges based on an internal current source until the voltage at the CT pin exceedsthatoftheinternalreferencevoltage. The time delay is determined by the value of the external capacitor C : t ≈ 2.6 × 104 × C , where C is in T d T T farads(F)andt isinseconds(s). d The current source to charge the timing capacitor varies ±15%. Reference Voltage 2 is approximately 1.8 V and varies approximately ±5%. Once the timing capacitor charges, it discharges to about 0.6 V, not completely to 0V. 8.4 Device Functional Modes Figure11displayshowtheRESETandRESEToutputpinsrespondtothechangeinthetheSENSEand RESIN input pins.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information Figure 12 shows an application where the TL7705B device is being used to sense the voltage supply for a microcontroller that is supplied with 5 V. If the voltage supply drops below the threshold voltage, the RESET pin ispulledLOW,signalingthemicrocontrollertoreset. 9.2 Typical Application TL7705B Copyright © 2016, Texas Instruments Incorporated Figure12. ResetControllerSchematicforaMicroprocessor 9.2.1 DesignRequirements The external components required include the decoupling capacitor for the REF pin and the timing capacitor for the CT pin.

SystemResetControllerWithUndervoltageSensing When the TL770xB SENSE terminal is used to monitor V , TI recommends a current-limiting resistor in series CC with C . During normal operation, the timing capacitor is charged by the onboard current source to approximately T V or an internal voltage clamp (≈7.1-V Zener), whichever is less. When the circuit then is subjected to an CC undervoltage condition during which V is rapidly slewed down, the voltage on CT exceeds that on V . This CC CC forward biases a secondary path internally, which falsely activates the outputs. A fault is indicated when V CC dropsbelowV ,notwhenV fallsbelowV . (CT) SENSE T– Addingtheexternalresistor,R ,preventsfalsetriggering.Itsvalueiscalculatedasfollows: T (V –V )/R (CT) T- T where • V =V or7.1V,whicheverisless (CT) CC • V =4.55V(nom) T– • R =valueofseriesresistorrequired (1) T ForV =5V CC (5–4.55)/R <1mA (2) T Therefore, R >450Ω (3) T Usinga20%-toleranceresistor,R shouldbegreaterthan560 Ω. T Adding this series resistor changes the duration of the reset pulse by no more than 10%. R extends the T discharge of C , but also skews the V threshold. These effects tend to cancel one another. The precise T (CT) percentage change can be derived theoretically, but the equation is complicated by this interaction and is dependentuponthedurationofthesupply-voltagefaultcondition. Both outputs of the TL770xB must be terminated with similar value resistors, even when only one is being used. This prevents unwanted plateauing in either output waveform during switching, which may be interpreted as an undefinedstateordelaysystemreset.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. Addendum-Page 2

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.
