## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | D | passive | Drain, P-channel MOSFET drain (VDS -40 V, ID -5 A at TC=25°C); tied to the other drain pins. |
| 2 | D | passive | Drain, P-channel MOSFET drain (VDS -40 V, ID -5 A at TC=25°C); tied to the other drain pins. |
| 3 | G | input | Gate, VGS limit ±20 V with threshold VGS(th) of -1.0 V min to -3.0 V max at ID=-250µA. |
| 4 | S | passive | Source, P-channel MOSFET source with continuous source current of -5 A max through the body diode. |
| 5 | D | passive | Drain, P-channel MOSFET drain (VDS -40 V, ID -5 A at TC=25°C); tied to the other drain pins. |
| 6 | D | passive | Drain, P-channel MOSFET drain (VDS -40 V, ID -5 A at TC=25°C); tied to the other drain pins. |
