Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | IC reference ground; also serves as the source of the internal power MOSFET. Tie pins 1 and 2 together to the SR return. |+| 2 | GND | power_in | IC reference ground; also serves as the source of the internal power MOSFET. Tie pins 1 and 2 together to the SR return. |+| 3 | VDD | power_in | IC supply pin. Absolute max 9 V DC; internally regulated from Drain to ~7.1 V (Drain=12V) with a 9 V clamp at 5 mA. VDD_ON ≈ 3.1 V, VDD_OFF ≈ 2.8 V (UVLO). Decouple to GND. |+| 4 | Vo | input | VDD supply configuration pin. Selects the VDD powering scheme (HV internal supply from Drain, or Vo LDO supply for Low-Side 12 V systems) - see functional description in the datasheet. |+| 5 | Drain | power_in | Drain of the internal power MOSFET (SR switch). Operating voltage range −0.3 to 80 V; MOSFET breakdown VBR = 80 V. Tie pins 5-8 together for current handling. |+| 6 | Drain | power_in | Drain of the internal power MOSFET (SR switch). Operating voltage range −0.3 to 80 V; MOSFET breakdown VBR = 80 V. Tie pins 5-8 together for current handling. |+| 7 | Drain | power_in | Drain of the internal power MOSFET (SR switch). Operating voltage range −0.3 to 80 V; MOSFET breakdown VBR = 80 V. Tie pins 5-8 together for current handling. |+| 8 | Drain | power_in | Drain of the internal power MOSFET (SR switch). Operating voltage range −0.3 to 80 V; MOSFET breakdown VBR = 80 V.
