TCM809SENB713

Microchip Tech · Supervisor And Reset ICs · SOT-23-3

TCM809SENB713 from Microchip Tech, 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.
2 RESET output Active-low push-pull reset output (TCM809) that stays low while VDD is below the reset threshold and for 240 ms (140 ms minimum) after VDD rises above it, and remains valid down to VDD = 1.0V.
3 VDD power_in Supply voltage being monitored (+2.5V, +3.0V, +3.3V or +5.0V nominal), absolute maximum 6.0V.
