GR · Gate Drivers · SOP-8
GR2103 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 V to 20 V (absolute max 25 V), with UVLO trip at 9.8 V max. |
| 2 | HIN | input | High-side logic input, in phase with HO, 3.3 V/5 V compatible with VIH min 2.7 V and VIL max 0.8 V. |
| 3 | LIN | input | Active-low low-side logic input (LO is inverted relative to LIN), 3.3 V/5 V compatible with VIH min 2.7 V and VIL max 0.8 V. |
| 4 | GND | power_in | Ground. |
| 5 | LO | output | Low-side gate drive output, swings 0 V to VCC. |
| 6 | VS | power_in | High-side floating supply return (offset) voltage, recommended -5 V to 600 V. |
| 7 | HO | output | High-side gate drive output, swings from VS to VB. |
| 8 | VB | power_in | High-side floating absolute supply voltage, recommended VS+10 V to VS+20 V (absolute max 625 V). |
