## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | D | passive | Drain terminal of the dual N-channel MOSFET, rated for a drain-source voltage (VDSS) of 20 V. |
| 2 | S1 | passive | Source terminal of channel 1 of the dual N-channel MOSFET. |
| 3 | S1 | passive | Source terminal of channel 1 of the dual N-channel MOSFET (second S1 pad shown in the pin assignment). |
| 4 | G1 | input | Gate terminal of channel 1; gate-source voltage is rated at ±12 V. |
| 5 | G2 | input | Gate terminal of channel 2; gate-source voltage is rated at ±12 V. |
| 6 | S2 | passive | Source terminal of channel 2 of the dual N-channel MOSFET. |
| 7 | S2 | passive | Source terminal of channel 2 of the dual N-channel MOSFET (second S2 pad shown in the pin assignment). |
| 8 | D | passive | Drain terminal of the dual N-channel MOSFET, rated for a drain-source voltage (VDSS) of 20 V. |
