## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S | passive | Source of the N-channel MOSFET, one of three source pins (labelled S S S G on the package drawing). |
| 2 | S | passive | Source of the N-channel MOSFET, one of three source pins (labelled S S S G on the package drawing). |
| 3 | S | passive | Source of the N-channel MOSFET, one of three source pins (labelled S S S G on the package drawing). |
| 4 | G | input | Gate of the N-channel MOSFET; VGS absolute maximum is ±20 V, with VGS(th) of 1.5 V min to 2.5 V max at 250 uA. |
| 5 | D | passive | Drain of the N-channel MOSFET, one of the four drain leads joined to the drain pad; VDS is 30 V max. |
| 6 | D | passive | Drain of the N-channel MOSFET, one of the four drain leads joined to the drain pad; VDS is 30 V max. |
| 7 | D | passive | Drain of the N-channel MOSFET, one of the four drain leads joined to the drain pad; VDS is 30 V max. |
| 8 | D | passive | Drain of the N-channel MOSFET, one of the four drain leads joined to the drain pad; VDS is 30 V max. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
