Shanghai Siproin Microelectronics · Supervisor And Reset ICs · SOT-89-3
H7027A-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, Hi-Z when VDD>VDET(+) and pulled to VSS when VDD≤VDET(-); H7027A-1 guarantees at least 0.5 mA sink current at VDD=2V, VOUT=0.2V. |
| 2 | VIN | power_in | Supply and voltage-sense input, operating range 1.5V to 16V with an absolute maximum of -0.3V to 16V. |
| 3 | GND | power_in | Ground (VSS) reference pin. |
