APX823-40W5G-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-25

APX823-40W5G-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 that is asserted when VCC rises above 1.1V and stays low while VCC is below VTH- (4.00V typ. for the -40 option), then returns high after the 200ms typ. delay td.
2 GND power_in Ground.
3 MR input Active-low manual reset input with an internal 60kΩ typ. pull-up, where a low level causes RESET to become active and pulse width of at least 100ns is required.
4 WDI input Watchdog input triggered by a positive or negative transition, where failing to retrigger within the 1.6s typ. time-out (1.12s min, 2.4s max) asserts RESET for td and leaving it unconnected disables the watchdog.
5 VCC power_in Operating voltage input rated 1.1V to 5.5V recommended and 6.0V absolute maximum, with a 0.1μF ceramic bypass capacitor recommended near the supply terminals.
