APX823-46W5G-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-25

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.
