HT7022-1

UMW · Supervisor And Reset ICs · SOT-89-3

HT7022-1 from UMW, in a SOT-89-3. 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 OUT output Chip output; the datasheet gives the absolute output voltage range as GND-0.3 V to VDD+0.3 V.
2 VDD power_in Chip input supply; operating voltage is 1.5 V to 12 V, with an absolute maximum input voltage of 15 V.
3 GND power_in Chip ground reference pin.
