# EG27322

**EG Micro** · Gate Drivers · SOP-8

EG27322 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 | VDD | power_in | Chip supply pin with an operating range of 5 V to 25 V and built-in VDD undervoltage protection (turn-on 4.5 V, turn-off 4.1 V). |
| 2 | IN | input | Logic input that turns the power switch on when high (1) and off when low (0), with a logic input range of -6 V to 25 V and an internal 400 kΩ pull-down; a floating input drives the output low. |
| 3 | NC | unconnected | Pin is left floating (悬空) per the datasheet pin description and is not used. |
| 4 | AGND | power_in | Input signal ground for the logic input circuit. |
| 5 | PGND | power_in | Power ground for the output driver stage. |
| 6 | OUTB | output | Driver output that sinks up to 8 A of current (IO- 8 A, PW ≤ 10 µs). |
| 7 | OUTA | output | Driver output that sources up to 9 A of current (IO+ 9 A, PW ≤ 10 µs). |
| 8 | VDD | power_in | Chip supply pin, tied internally to pin 1 and specified for 5 V to 25 V operation. |
