APX809S-44SR-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23

APX809S-44SR-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 Push-pull active-low reset output on the APX809S (SR package), which is guaranteed to be in the correct logic state for VCC down to 1 V, with a 20 mA absolute maximum output current and a -0.3 V to 6.0 V voltage rating.
2 GND power_in Ground reference pin for the device, with the VCC operating range of 1.0 V to 5.5 V referenced to it.
3 VCC power_in Operating voltage input with a recommended supply range of 1.0 V to 5.5 V and an absolute maximum rating of -0.3 V to 6.0 V.
