## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low-side supply pin, recommended operating range 10 V to 20 V referenced to VSS, with an absolute maximum of -0.3 V to 25 V. |
| 2 | IN | input | High-side logic signal input compatible with 3.3 V, 5 V and 15 V logic, with VIH minimum 2.5 V and VIL maximum 0.8 V (VCC = 10 V to 20 V). |
| 3 | SD | input | Low-side logic signal input (shutdown input per the block diagram), with the same logic threshold limits as IN. |
| 4 | VSS | power_in | Ground reference for all voltage parameters in the datasheet. |
| 5 | LO | output | Low-side gate driver output referenced to VSS, with typical source current of 290 mA and sink current of 600 mA (pulse width up to 10 µs). |
| 6 | VS | power_in | High-side floating ground reference, rated for VB - 25 V to VB + 0.3 V absolute maximum, with recommended operation between -8 V and 200 V (up to 250 V per the recommended range table), and dVS/dt tolerance of ±50 V/ns. |
| 7 | HO | output | High-side gate driver output referenced to VS, with output voltage limited to VS - 0.3 V to VB + 0.3 V. |
| 8 | VB | power_in | High-side floating bootstrap supply, recommended VS + 10 V to VS + 20 V, with an absolute maximum of -0.3 V to 275 V. |
