TPS36BA38ACADDFRQ1

Texas Instruments · Supervisor And Reset ICs · TSOT-23-8

TPS36BA38ACADDFRQ1 from Texas Instruments, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SET0 input Logic input for watchdog window ratio selection; in combination with SET1 determines the open-window-to-close-window ratio; state sampled at power-up or after RESET event.
2 CWD input Programmable watchdog timeout input; connect external capacitor (1.5 nF to 1000 nF) between this pin and GND to set close-window timer using internal current source calibration.
3 CRST input Programmable reset timeout pin; connect external capacitor (1.5 nF to 1800 nF) between this pin and GND to program RESET output assertion delay time.
4 GND power_in Ground pin providing 0 V reference potential; recommend 0.1 µF bypass capacitor connection to VDD.
5 SET1 input Logic input for watchdog configuration; in combination with SET0 selects open-window ratio; state sampled at power-up or after RESET event.
6 WDI input Watchdog input; falling edge transition required during open-window period (tWO) to prevent RESET assertion; early fault if edge detected during close-window period (tWC).
7 RESET output Reset output, open-drain configuration; asserted active-low for 25 ms (programmed) when VDD falls below 2.90 V threshold or watchdog error occurs; requires external pull-up resistor to VDD.
8 VDD power_in Supply voltage pin; operating range 0.9 V to 6.0 V with quiescent current 250 nA typical; 0.1 µF bypass capacitor to GND recommended.
