H7022A-1 from Shanghai Siproin Microelectronics, 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 | VOUT | output | Detector output that is Hi-Z when VDD is above VDET(+) and pulled to VSS when VDD is at or below VDET(-) (2.2V typical detection voltage, 2.156V to 2.244V); IOL min 0.5mA at VOUT=0.2V, VDD=2V. |
| 2 | VIN | power_in | Supply and voltage sense input, operating range 1.5V to 16V, absolute maximum -0.3V to 16V. |
| 3 | GND | power_in | Ground (VSS) reference pin for the voltage detector. |
