## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S1 | passive | Source of MOSFET 1. Return terminal for the first N-channel MOSFET channel; VGS rated ±20V, IS continuous up to 5A (limited by total power dissipation). |
| 2 | G1 | input | Gate of MOSFET 1. Control input for the first N-channel MOSFET; VGS(th)=1.0-2.5V (typ 1.7V), VGS absolute max ±20V. |
| 3 | S2 | passive | Source of MOSFET 2. Return terminal for the second N-channel MOSFET channel; VGS rated ±20V, IS continuous up to 5A (limited by total power dissipation). |
| 4 | G2 | input | Gate of MOSFET 2. Control input for the second N-channel MOSFET; VGS(th)=1.0-2.5V (typ 1.7V), VGS absolute max ±20V. |
| 5 | D2 | passive | Drain of MOSFET 2 (paired with pin 6 for reduced RDS(ON) and improved thermal). VDS rated 100V, ID continuous 2.3A @ TA=25°C. |
| 6 | D2 | passive | Drain of MOSFET 2 (paired with pin 5 for reduced RDS(ON) and improved thermal). VDS rated 100V, ID continuous 2.3A @ TA=25°C. |
