## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low-side supply pin; recommended operating range is 10 V to 20 V, absolute maximum is 25 V, and the UVLO thresholds are 8.9 V rising and 8.2 V falling (typical). |
| 2 | HIN | input | High-side logic input with VIH minimum 2.5 V and VIL maximum 0.8 V, referenced to VSS and compatible with 3.3 V, 5 V and 15 V logic; input voltage must stay within 0 to VCC. |
| 3 | LIN | input | Low-side logic input with VIH minimum 2.5 V and VIL maximum 0.8 V, referenced to VSS and compatible with 3.3 V, 5 V and 15 V logic; input voltage must stay within 0 to VCC. |
| 4 | VSS | power_in | Ground reference pin; all voltage ratings in the datasheet are referenced to VSS. |
| 5 | LO | output | Low-side gate driver output that sources up to 300 mA and sinks up to 600 mA (pulse width 10 µs or less), swinging between 0 V and VCC. |
| 6 | VS | power_in | High-side floating ground reference; recommended range is -9 V to 700 V, dV/dt tolerance is ±50 V/ns, and it tolerates a 50 ns transient down to VSS-50 V (design-guaranteed). |
| 7 | HO | output | High-side gate driver output referenced to VS, with VHO between VS and VB. |
| 8 | VB | power_in | High-side floating supply; recommended range is VS + 10 V to VS + 20 V, with an absolute maximum of 725 V referenced to VSS. |
