APX809-23SAG-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23

APX809-23SAG-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.
2 RESET output Active-low push-pull reset output for the APX809, asserted when VCC falls below the reset threshold and held for the reset timeout period (140 to 280 ms) after VCC rises above it, valid down to VCC = 1V.
3 VCC power_in Operating voltage input, recommended 1.1V to 5.5V (absolute maximum -0.3 to +6.0V).
