# EG2107

**EG Micro** · Gate Drive ICs · SOP-8

EG2107 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 | Chip supply input, rated 8V to 20V; a 0.1uF high-frequency bypass capacitor is recommended to reduce high-frequency noise at the supply pin. |
| 2 | IN | input | Active-high logic input that controls the high-side MOSFET: 0 turns the power MOS off and 1 turns it on. |
| 3 | CS | input | Overcurrent protection input for cycle-by-cycle protection; when it is high, HO and LO are both turned off. |
| 4 | GND | power_in | Chip ground pin, to be connected in common with the MCU ground. |
| 5 | LO | output | Drives the low-side N-channel power MOSFET on and off; sink current up to 1.3A and source current up to 0.8A as stated in the datasheet. |
| 6 | VS | power_in | High-side floating ground reference for the high-side driver, operating within the VB-25V to VB+0.3V range stated in the absolute maximum ratings. |
| 7 | HO | output | Drives the high-side N-channel power MOSFET on and off, referenced to VS, with the same 0.8A source and 1.3A sink drive capability as LO. |
| 8 | VB | power_in | Floating high-side supply for the bootstrap circuit, with an absolute maximum rating of 550V as stated in the datasheet. |
