EG2104S from EG Micro, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Chip power supply input, 9V-20V. A 0.1uF high-frequency bypass capacitor is required at this pin to reduce input noise.
2 IN input Logic input control signal that determines MOSFET on/off state. Logic '0' sets LO high and HO low; logic '1' sets HO high and LO low. Internal 200k pull-down resistor.
3 SD input Active-low shutdown input. Logic '1' allows LO/HO to follow IN; logic '0' forces both LO and HO outputs low. Internal 200k pull-down resistor.
4 GND power_in Chip ground reference.
5 LO output Low-side gate drive output. Controls the low-side MOSFET/IGBT on/off. Output current capability +/-1.0A/1.5A.
6 VS power_in High-side floating return (source of high-side MOSFET). Reference node for the high-side driver, can swing up to 600V.
7 HO output High-side gate drive output. Controls the high-side MOSFET/IGBT on/off, referenced to VS. Output current capability +/-1.0A/1.5A.
8 VB power_in High-side floating bootstrap supply. Connected via bootstrap diode from VCC and bootstrap capacitor to VS. Provides gate drive supply for the high-side driver.

Provenance

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

  • Datasheet: EG Micro datasheet (12 pp, sha256 e1bdec7bd0962ced, retrieved 2026-08-17, 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: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
