H7044A-1NPR 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; per the output table VOUT is high-impedance when VDD > VDET(+) and at VSS when VDD ≤ VDET(-), and the N suffix of this MPN denotes an NMOS open-drain output. |
| 2 | VIN | power_in | Supply voltage input with an operating voltage of 1.5 V to 16 V and an absolute maximum supply input rating of -0.3 V to 16 V. |
| 3 | GND | power_in | Ground connection. |
