TPS3823-25DBVR 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 | Low-level active reset output with push-pull output stage; VOL = 0.4V max at 1mA, VOH = 0.8×VDD at -20µA for VDD = VIT- + 0.2V. |
| 2 | GND | power_in | Ground connection; reference potential for the device. |
| 3 | MR | input | Manual reset input; pulling to low level (VIL = 0.3×VDD) forces RESET active and holds it low with timeout duration after MR returns high; leave unconnected or tie to VDD when unused; 90kΩ internal pull-up. |
| 4 | WDI | input | Watchdog timer input; if held high or low beyond watchdog timeout period (0.9-2.5s nominal for TPS3823-25), triggers RESET active; timer resets on falling edge or RESET active; device generates internal pulses if left floating to prevent false watchdog reset. |
| 5 | VDD | power_in | Power supply voltage input from 1.1V to 5.5V; supplies device power and is monitored for voltage supervision at threshold 2.25V (TPS3823-25 nominal). |
