Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TPS3824-50QDBVRQ1 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 reset output with a push-pull output stage; it is held low while VDD is below the threshold VIT− and for the delay time td after VDD rises above the threshold. |
| 2 | GND | power_in | Ground connection for the device. |
| 3 | RESET | output | Active-high reset output with a push-pull output stage, present only on the TPS3824-xx-Q1; it is high while VDD is below VIT− and while reset is asserted. |
| 4 | WDI | input | Watchdog timer input; if WDI stays high or low longer than the timeout period, a reset is triggered, and the timer is cleared by a falling edge on WDI or when reset is asserted, so WDI must be driven low or high rather than left high-impedance. |
| 5 | VDD | power_in | Supply voltage that powers the device and is monitored; the recommended operating range is 1.1 V to 5.5 V. |
