GR2103

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).

  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: gr2103-etched.step / gr2103-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr2103.step / gr2103.glb are the bare package body.

Provenance

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

  • Datasheet: GR datasheet (7 pp, sha256 abbc992641a811b6, 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.
