## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low-side and logic fixed supply, recommended 10 V to 20 V, with absolute maximum of 25 V referenced to COM. |
| 2 | HIN | input | Logic input for the high-side gate driver output HO, in phase with HO; logic-high threshold is at least 2.5 V and logic-low at most 0.8 V. |
| 3 | LIN | input | Logic input for the low-side gate driver output LO, out of phase with LO; logic-high threshold is at least 2.5 V and logic-low at most 0.8 V. |
| 4 | COM | power_in | Low-side return; all voltage parameters are referenced to this pin. |
| 5 | LO | output | Low-side gate drive output, swinging between COM and VCC. |
| 6 | VS | power_in | High-side floating supply return, rated up to 600 V with dVS/dt limited to 50 V/ns. |
| 7 | HO | output | High-side gate drive output, referenced to VS and swinging between VS and VB. |
| 8 | VB | power_in | High-side floating supply, recommended VS + 10 V to VS + 20 V, with absolute maximum of 625 V. |
