APX809-40SAG-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23-3

APX809-40SAG-7 from Diodes Incorporated, in a SOT-23-3. 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 for the device.
2 RESET output Push-pull active-low reset output for APX809, guaranteed logic low for VCC above 1V and held low for the reset timeout period (140 to 280ms) after VCC rises above the threshold.
3 VCC power_in Operating voltage input, supply range 1.1V to 5.5V recommended, absolute maximum -0.3 to +6.0V.
