APX823-46W5G-7 from Diodes Incorporated, in a SOT-25. 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, asserted when VCC falls below VTH- (or on MR low or watchdog timeout) and held for the delay time td (140-280 ms, 200 ms typ) after VCC recovers. |
| 2 | GND | power_in | Ground. |
| 3 | MR | input | Active-low manual reset input with internal ~60 kΩ pull-up; a low level (below 0.3×VCC) forces RESET active. |
| 4 | WDI | input | Watchdog input triggered by a positive or negative transition; if not retriggered within the timeout ttout (1.6 s typ) RESET is asserted, and leaving it unconnected disables the watchdog. |
| 5 | VCC | power_in | Operating supply voltage input, 1.1 V to 5.5 V recommended, with a 0.1 µF ceramic bypass capacitor placed nearby. |
