**Texas Instruments** · AC-DC Controllers And Regulators · VSSOP-8-0.65mm

LM74610QDGKTQ1 from Texas Instruments, in a VSSOP-8-0.65mm. 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 that connects to an external charge pump capacitor; VcapH to VcapL is limited to -0.3 V to 7 V. |
| 2 | Gate Pull Down | output | Connects to the gate of the external MOSFET to pull it down for fast turn-off in the case of reverse polarity; Gate Pull Down to VcapL is limited to -0.3 V to 7 V. |
| 3 | NC | unconnected | No connect; leave floating or connect to the Anode pin. |
| 4 | Anode | passive | Anode of the diode, connected to the source of the external MOSFET; Anode to VcapL is limited to -0.3 V to 3 V, and there is no positive voltage limit on the Anode terminal. |
| 5 | NC | unconnected | No connect; leave floating or connect to the gate drive pin. |
| 6 | Gate Drive | output | Gate drive output that connects to the gate of the external MOSFET; Gate Drive to VcapL is limited to -0.3 V to 7 V. |
| 7 | VcapH | power_out | Charge pump output that connects to an external charge pump capacitor; VcapH to VcapL is limited to -0.3 V to 7 V. |
| 8 | Cathode | passive | Cathode of the diode, connected to the drain of the external MOSFET; Cathode to Anode is rated 42 V continuous (45 V for 2 ms transients). |
