GR3115 from GR, in a SOP-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 supply voltage; recommended 10 to 20 V, absolute maximum -0.3 to 25 V, with UVLO protection. |
| 2 | HIN | input | High-side logic input, in phase with HO, 3.3V/5V compatible, -0.3 to VCC+0.3 V. |
| 3 | LIN | input | Low-side logic input (active low, inverted relative to LO), 3.3V/5V compatible, -0.3 to VCC+0.3 V. |
| 4 | GND | power_in | Ground. |
| 5 | LO | output | Low-side gate drive output, 0 to VCC recommended, absolute maximum -0.3 to VCC+0.3 V. |
| 6 | VS | power_in | High-side floating supply return (floating ground), recommended -5 to 180 V, absolute maximum VB-25 to VB+0.3 V. |
| 7 | HO | output | High-side gate drive output, VS to VB recommended, absolute maximum VS-0.3 to VB+0.3 V. |
| 8 | VB | power_in | High-side floating absolute supply voltage, recommended VS+10 to VS+20 V, absolute maximum -0.3 to 205 V. |
