EG Micro · Gate Drive ICs · SOP-8

EG2104 from EG Micro, 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 input for the chip, specified at 2.8V to 20V; a high-frequency 0.1uF bypass capacitor is recommended to reduce high-frequency noise on the input.
2 IN input Logic input controlling the on/off state of the high-side (HO) and low-side (LO) MOS transistor outputs; IN=1 gives HO high and LO low, IN=0 gives LO high and HO low.
3 SD input Active-low logic input that forces HO and LO low when set to 0 and allows IN to control the outputs when set to 1.
4 GND power_in Ground terminal of the chip.
5 LO output Output that drives the low-side power MOS transistor on and off.
6 VS power_in High-side floating ground reference, the return for the high-side driver.
7 HO output Output that drives the high-side power MOS transistor on and off.
8 VB power_in High-side floating supply for the bootstrap circuit that powers the high-side driver.
