## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Low-side supply voltage, recommended 10 V to 20 V (absolute max 25 V) referenced to GND. |
| 2 | NC | unconnected | No connect pin. |
| 3 | IN1 | input | Logic input for high-side channel 1, 0 V to VDD, compatible with 3.3 V, 5 V and 15 V logic. |
| 4 | NC | unconnected | No connect pin. |
| 5 | IN2 | input | Logic input for high-side channel 2, 0 V to VDD, compatible with 3.3 V, 5 V and 15 V logic. |
| 6 | NC | unconnected | No connect pin. |
| 7 | GND | power_in | Ground reference for logic and low-side supply. |
| 8 | VS2 | passive | High-side floating return (offset) for channel 2, recommended -9 V to 700 V. |
| 9 | HO2 | output | High-side gate drive output for channel 2, swinging between VS and VB, with 350 mA source / 650 mA sink capability. |
| 10 | VB2 | power_in | High-side floating supply for channel 2, recommended VS+10 V to VS+20 V (absolute max 725 V). |
| 11 | NC | unconnected | No connect pin. |
| 12 | VS1 | passive | High-side floating return (offset) for channel 1, recommended -9 V to 700 V. |
| 13 | HO1 | output | High-side gate drive output for channel 1, swinging between VS and VB, with 350 mA source / 650 mA sink capability. |
| 14 | VB1 | power_in | High-side floating supply for channel 1, recommended VS+10 V to VS+20 V (absolute max 725 V). |
