Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low-side and logic fixed supply; recommended operating range is 10V to 20V, with absolute maximum -0.3V to 25V referenced to COM. |
| 2 | HIN | input | Logic input for the high-side gate driver output (HO), in phase with HO; logic-1 threshold is 2.5V minimum and logic-0 threshold is 0.8V maximum, compatible with 3.3V and 5V logic. |
| 3 | LIN | input | Logic input for the low-side gate driver output (LO), in phase with LO; logic-1 threshold is 2.5V minimum and logic-0 threshold is 0.8V maximum, compatible with 3.3V and 5V logic. |
| 4 | COM | power_in | Low-side return; all voltage parameters are absolute voltages referenced to COM. |
| 5 | LO | output | Low-side gate drive output, swinging between 0 V and VCC; typical source/sink pulsed current is 4.0A (PW ≤ 10µs). |
| 6 | VS | power_in | High-side floating supply return; the logic remains operational for VS from -5V to +600V, with the high-side output referenced to this pin. |
| 7 | HO | output | High-side gate drive output, swinging between VS and VB; typical source/sink pulsed current is 4.0A (PW ≤ 10µs). |
| 8 | VB | power_in | High-side floating supply; recommended VB is VS + 10V to VS + 20V, with absolute maximum VB of 625V (referenced to COM). |
