VN751STR from STMicroelectronics, in a SO-8. 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 | GND | power_in | Ground pin, with a maximum DC reverse ground pin current of -200 mA, and the device turns off automatically if this pin is disconnected. |
| 2 | INPUT | input | CMOS-compatible control input with VIL max 1.25 V, VIH min 3.25 V and DC input current rated -1 to +10 mA. |
| 3 | STATUS | output | Open-drain status output with status low voltage max 0.5 V at ISTAT = 1.6 mA and DC status current rated -1 to +10 mA. |
| 4 | NC | unconnected | Not connected pin; the datasheet states no function or limits for it. |
| 5 | VCC | power_in | Supply voltage pin, 5.5 V to 36 V operating with 45 V absolute maximum DC supply voltage, and shared with pins 8 for the supply connection. |
| 6 | OUT | power_out | High-side power output to the load with RDS(on) typ 60 mOhm, current limit 2.7 A to 6.0 A, and reverse DC output current rated -5 A. |
| 7 | OUT | power_out | High-side power output to the load with RDS(on) typ 60 mOhm, current limit 2.7 A to 6.0 A, and reverse DC output current rated -5 A. |
| 8 | VCC | power_in | Supply voltage pin, 5.5 V to 36 V operating with 45 V absolute maximum DC supply voltage, and shared with pin 5 for the supply connection. |
