TPS3813I50QDBVRQ1

Texas Instruments · Monitors & Reset Circuits · SOT-23-6

TPS3813I50QDBVRQ1 from Texas Instruments, in a SOT-23-6. 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 WDI input Watchdog timer input that must be driven at all times and not left floating.
2 GND power_in Ground.
3 WDT input Programmable watchdog delay input, set by connecting to GND or VDD or by using an external capacitor.
4 VDD power_in Supply voltage and supervising input, recommended operating range 2 V to 6 V (absolute maximum 7 V).
5 WDR input Selectable watchdog window ratio input that must be tied to VDD or GND and not left floating.
6 RESET output Open-drain active-low reset output, asserted when VDD drops below VIT.
