Shanghai Siproin Microelectronics · Monitors & Reset Circuits · SOT-89-3
H7039A-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(-); the datasheet gives 1.2 mA minimum sink current at VOUT=0.2V and VDD=2V for the 3.9V part. |
| 2 | VIN | power_in | Supply and voltage sense input with operating voltage 1.5V to 16V and absolute maximum -0.3V to 16V; the 3.9V part detects at 3.900V typ (3.822V to 3.978V). |
| 3 | GND | power_in | Ground (VSS) reference pin for the voltage detector. |
