APX803-44SAG-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23

APX803-44SAG-7 from Diodes Incorporated, in a SOT-23. 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 GND power_in Ground reference for the device.
2 RESET output Active-low open-drain reset output that is asserted when VCC falls below the threshold and stays low for the reset timeout period (140ms min, 200ms typ) after VCC rises above it; guaranteed low for VCC > 1V, and the output voltage is rated 0 to 5.5V.
3 VCC power_in Operating voltage input and monitored supply, recommended 1.1V to 5.5V, with an absolute maximum of 6.0V.
