GR · Gate Drivers · SOP-8

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: GR datasheet (6 pp, sha256 eba43304e172cb25, retrieved 2026-10-09, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
