TPS3124J12DBVT from Texas Instruments, in a SOT-23-5. 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 | RESET | output | Active-low output reset signal driven to a logic low when VDD falls below the negative threshold VIT-, remaining asserted for delay tD after VDD rises above VIT+ = VIT- + VHYS. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | RESET | output | Active-high output reset signal driven to a logic high when VDD falls below the negative threshold VIT-, remaining asserted for delay tD after VDD rises above VIT+ = VIT- + VHYS. |
| 4 | WDI | input | Watchdog timer input; if WDI remains high or low longer than the timeout period, reset is triggered, and the timer clears when reset is asserted or WDI sees a rising or falling edge. |
| 5 | VDD | power_in | Input supply voltage pin; good analog practice is to place a 0.1µF ceramic capacitor close to this pin, with recommended VDD of 0.9 V to 3.3 V. |
