## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Logic input for the high and low side gate driver outputs (HO and LO), in phase with HO and referenced to COM, with VIH min 2.7 V and VIL max 0.8 V over VCC 10 V to 20 V and an internal 5.2 V zener clamp. |
| 2 | SD | input | Logic shutdown input referenced to COM, with positive-going threshold min 2.7 V and negative-going threshold max 0.8 V, and an internal 5.2 V zener clamp. |
| 3 | COM | power_in | Low side return and reference for the logic inputs and the LO/HO output voltages; all absolute voltage ratings are referenced to COM. |
| 4 | LO | output | Low side gate drive output, operating between 0 V and VCC, with 1.4 A source / 1.8 A sink output current capability. |
| 5 | VCC | power_in | Low side and logic fixed supply, recommended range 10 V to 20 V with an absolute maximum of 25 V (undervoltage lockout applies). |
| 6 | VS | power_in | High side floating supply return, rated for offset of up to 600 V (recommended) with dVS/dt transients limited to 50 V/ns. |
| 7 | HO | output | High side gate drive output, operating between VS and VB, in phase with the IN input. |
| 8 | VB | power_in | High side floating supply, recommended VS + 10 V to VS + 20 V with an absolute maximum of 625 V, supplying the high side driver through a bootstrap circuit. |
