APX809-44SAG-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-23

APX809-44SAG-7 from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the supervisor. 0V return for VCC and the push-pull RESET output stage.
2 /RESET output Active-low push-pull reset output (APX809 variant). Driven low whenever VCC is below the 4.38V threshold and held low for the reset timeout period (200ms typ, 140-280ms) after VCC rises above threshold. VOL <= 0.3V at ISINK=1.2mA; VOH >= 0.8*VCC at ISOURCE=500µA. Guaranteed valid down to VCC=1V.
3 VCC power_in Operating voltage input, monitored against the internal 4.38V reset threshold (APX809-44 option). Recommended operating range 1.1V to 5.5V; absolute max 6.0V. Recommended 100nF decoupling capacitor to GND.
