APX823-31W5G-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-25

APX823-31W5G-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 (RESET with overbar) that is asserted when VCC is below VTH- (3.08V typ. for the -31 option) or MR is low or the watchdog times out, and returns high after the 200ms typ. delay td.
2 GND power_in Ground.
3 WDI input Watchdog input triggered by a positive or negative transition, with a time-out ttout of 1.6s typ.; leaving it unconnected disables the watchdog.
4 MR input Active-low manual reset input with an internal 60kΩ pull-up (typ.) that forces RESET active when pulled low.
5 VCC power_in Operating voltage input, 1.1V to 5.5V recommended (6.0V absolute maximum), with a 0.1µF ceramic bypass capacitor recommended close to the pin.
