## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low-side and logic fixed supply, with a recommended range of 5V to 20V. |
| 2 | HIN | input | Logic input for the high-side gate driver output (HO), in phase with HO, compatible with 3.3V, 5V and 15V logic with VIH minimum 2.5V and VIL maximum 0.8V. |
| 3 | LIN | input | Logic input for the low-side gate driver output (LO), in phase with LO, compatible with 3.3V, 5V and 15V logic with VIH minimum 2.5V and VIL maximum 0.8V. |
| 4 | COM | power_in | Low-side return; all voltage parameters are referenced to COM. |
| 5 | LO | output | Low-side gate drive output, with typical pulsed source current of 200mA and sink current of 350mA (PW ≤ 10µs). |
| 6 | VS | power_in | High-side floating supply return, with a floating supply offset voltage rated from 1V to 600V and an allowable offset transient of 50 V/ns. |
| 7 | HO | output | High-side gate drive output, in phase with HIN, referenced to VS and driven between VS and VB. |
| 8 | VB | power_in | High-side floating supply, which must be held between VS + 5V and VS + 20V. |
