APX809S05-31SA-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-23

APX809S05-31SA-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 pin.
2 RESET output Active-low push-pull reset output that asserts when VCC falls below the reset threshold and stays asserted for the reset timeout period (20ms min, 50ms typ, 70ms max for the APX809S05 option) after VCC rises above it.
3 VCC power_in Operating voltage input, recommended range 1.0V to 5.5V (absolute maximum -0.3V to 6.0V).
