## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S | passive | Source terminal of the N-channel MOSFET. Pin 1 is one of four source pins (1-4) ganged together in the DFN5x6-8L package. |
| 2 | S | passive | Source terminal of the N-channel MOSFET. Pin 2 is ganged with pins 1, 3, 4 as Source. |
| 3 | S | passive | Source terminal of the N-channel MOSFET. Pin 3 is ganged with pins 1, 2, 4 as Source. |
| 4 | G | input | Gate terminal of the N-channel MOSFET. VGS max ±20V; typical VGS(th) = 1.5V (1.0V min, 2.0V max). Drives the MOSFET on/off. |
| 5 | D | passive | Drain terminal of the N-channel MOSFET. Pin 5 is one of four drain pins (5-8) ganged together and typically connected to the exposed thermal pad on the DFN5x6-8L package. VDS max = 40V. |
| 6 | D | passive | Drain terminal of the N-channel MOSFET. Ganged with pins 5, 7, 8 and the exposed pad. |
| 7 | D | passive | Drain terminal of the N-channel MOSFET. Ganged with pins 5, 6, 8 and the exposed pad. |
| 8 | D | passive | Drain terminal of the N-channel MOSFET. Ganged with pins 5, 6, 7 and the exposed pad. |
