Texas Instruments · Supervisor And Reset ICs · SOT-23-6
TPS3813J25DBVR 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; must be driven at all times and not left floating. |
| 2 | GND | power_in | Ground |
| 3 | WDT | input | Programmable watchdog delay input |
| 4 | VDD | power_in | Supply voltage and supervising input |
| 5 | WDR | input | Selectable watchdog window ratio input; must be tied to VDD or GND and not left floating. |
| 6 | RESET | output | Open-drain reset output |
