Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low-side supply pin, recommended operating range 6 V to 20 V referenced to VSS, with an absolute maximum of -0.3 V to 25 V. |
| 2 | HIN | input | High-side logic input referenced to VSS, with a logic-high threshold of at least 2.5 V and a logic-low threshold of at most 0.8 V, compatible with 3.3 V, 5 V and 15 V logic. |
| 3 | LIN | input | Low-side logic input referenced to VSS, with a logic-high threshold of at least 2.5 V and a logic-low threshold of at most 0.8 V, compatible with 3.3 V, 5 V and 15 V logic. |
| 4 | VSS | power_in | Ground reference pin to which all voltage parameters (VCC, VB, VIN, VLO, VHO and the rated limits) are referenced. |
| 5 | LO | output | Low-side gate driver output with 4 A source and 4 A sink capability (pulsed, PW ≤ 10 µs) and a low-level voltage drop of at most 0.1 V at IO = 0 A. |
| 6 | VS | power_in | High-side floating ground (bootstrap return) that may swing from -9 V to 250 V in recommended operation, with a maximum dVS/dt of 50 V/ns and a transient capability down to VSS-50 V for 50 ns. |
| 7 | HO | output | High-side gate driver output referenced to VS, with 4 A source and 4 A sink capability (pulsed, PW ≤ 10 µs) and a high-level voltage drop of at most 1.5 V at IO = 0 A. |
| 8 | VB | power_in | High-side floating supply for the bootstrap circuit, recommended at VS + 6 V to VS + 20 V, with an absolute maximum of -0.3 V to 275 V. |
