Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | HIN1 | input | Logic input for the channel 1 high-side MOS transistor, active high: 1 turns the high-side switch on and 0 turns it off. |
| 2 | LIN1 | input | Logic input for the channel 1 low-side MOS transistor, active high: 1 turns the low-side switch on and 0 turns it off. |
| 3 | HIN2 | input | Logic input for the channel 2 high-side MOS transistor, active high: 1 turns the high-side switch on and 0 turns it off. |
| 4 | LIN2 | input | Logic input for the channel 2 low-side MOS transistor, active high: 1 turns the low-side switch on and 0 turns it off. |
| 5 | SD1 | bidirectional | Active-low logic signal that forces LO1 and HO1 outputs low when pulled low. |
| 6 | SD2 | bidirectional | Active-low logic signal that forces LO2 and HO2 outputs low when pulled low. |
| 7 | CINN1 | input | Negative input of comparator 1; comparator input voltage range is 0.1 V to VCC. |

| 13 | LO2 | output | Drives the gate of the channel 2 low-side power MOS transistor. |
| 14 | LO1 | output | Drives the gate of the channel 1 low-side power MOS transistor. |
| 15 | NC | unconnected | No internal connection; left floating (suspended). |
| 16 | NC | unconnected | No internal connection; left floating (suspended). |
| 17 | VS2 | power_in | High-side floating ground reference for channel 2. |
| 18 | HO2 | output | Drives the gate of the channel 2 high-side power MOS transistor. |
| 19 | VB2 | power_in | High-side floating supply for channel 2 (bootstrap supply node). |
| 20 | NC | unconnected | No internal connection; left floating (suspended). |
| 21 | NC | unconnected | No internal connection; left floating (suspended). |
| 22 | VS1 | power_in | High-side floating ground reference for channel 1. |
| 23 | HO1 | output | Drives the gate of the channel 1 high-side power MOS transistor. |
| 24 | VB1 | power_in | High-side floating supply for channel 1 (bootstrap supply node). |
