HG809TM3

HGSEMI · Supervisor And Reset ICs · SOT-23-3

HG809TM3 from HGSEMI, 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 Chip ground terminal; the datasheet gives no voltage limit for this pin.
2 RESET output Reset output (VRESET); with VCC=Vthmin and ISINK=1.2mA, VOL is at most 0.3V, and with VCC>Vthmax and ISOURCE=500uA, VOH is at least 0.8VCC.
3 VCC power_in Chip supply input, operating range 1.0V to 6.0V, with an absolute maximum of 6.5V.
