NCP5109BDR2G from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Low side and main power supply, with a gate drive supply range of 10 V to 20 V, an absolute maximum of −0.3 V to 20 V, and 23 V transient for 10 ms at 5 mA maximum. |
| 2 | IN_HI | input | Logic input for the high side driver, with output in phase; it is 3.3 V and 5 V logic compatible and rated −1.0 V to VCC + 0.3 V. |
| 3 | IN_LO | input | Logic input for the low side driver, with output in phase; it is 3.3 V and 5 V logic compatible and rated −1.0 V to VCC + 0.3 V. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | DRV_LO | output | Low side gate drive output with 250 mA source and 500 mA sink capability, rated −0.3 V to VCC + 0.3 V. |
| 6 | BRIDGE | power_in | Bootstrap return and high side floating supply return; rated −1 V to 200 V, with an allowable negative swing of −10 V for IN_LO signal propagation. |
| 7 | DRV_HI | output | High side gate drive output, rated VBRIDGE − 0.3 V to VBOOT + 0.3 V. |
| 8 | VBOOT | power_in | Bootstrap power supply for the high side floating supply, rated −0.3 V to 20 V relative to VBRIDGE. |
