APX809S-40SR-7

Diodes Incorporated · Monitors & Reset Circuits · SOT-23

APX809S-40SR-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 RESET output Active-low push-pull reset output (APX809S) that asserts when VCC falls below the preset threshold and stays asserted for at least 240ms (typ. 240ms) after VCC rises above it; valid down to VCC = 1V.
2 GND power_in Ground pin for the device.
3 VCC power_in Operating voltage input, recommended 1.0V to 5.5V (absolute maximum -0.3V to 6.0V).
