LM74670QDGKTQ1 from Texas Instruments, in a VSSOP-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 | VcapL | power_out | Charge Pump Output, connect to an external charge pump capacitor |
| 2 | Gate Pull Down | output | Connect to the gate of the external MOSFET for fast turn OFF in the case of reverse polarity |
| 3 | NC | unconnected | No connect. Leave floating or connect to Anode pin |
| 4 | Anode | input | Anode of the diode, connect to source of the external MOSFET |
| 5 | NC | unconnected | No connect. Leave floating or connect to gate drive pin |
| 6 | Gate Drive | output | Gate Drive output, Connect to the Gate of the external MOSFET |
| 7 | VcapH | power_out | Charge Pump Output, connect to an external charge pump capacitor |
| 8 | Cathode | output | Cathode of the diode, connect to Drain of the external MOSFET |
