SE809-HF-2.93V

Seaward Elec · Supervisor And Reset ICs · SOT-23

SE809-HF-2.93V from Seaward Elec, 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 reference pin for the SE809 supervisor.
2 RESET output RESET output remains low while Vcc is below the reset voltage threshold and for 150msec (typ) after Vcc rises above the reset threshold; the datasheet states the output is guaranteed valid down to VCC = 1V and is an active-low output.
3 Vcc power_in Supply voltage input monitored against the reset threshold; the datasheet gives an operating supply input range of 2.0 V to 5.5 V.
