EG2304 from EG Micro, in a SOP-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 LIN input Logic input for the low-side gate driver, active-high. '1' turns the low-side power MOSFET on; '0' turns it off. Internally pulled low via a 200 kΩ resistor so the LO output stays off when the input is floating. Accepts 3.3V/5V CMOS logic levels.
2 HIN input Logic input for the high-side gate driver, active-high. '1' turns the high-side power MOSFET on; '0' turns it off. Internally pulled low via a 200 kΩ resistor so the HO output stays off when the input is floating. Accepts 3.3V/5V CMOS logic levels.
3 VCC power_in Low-side chip supply input, operating range 10 V-20 V (features list gives 10 V-25 V range). A 1 μF high-frequency bypass capacitor to GND is recommended to reduce input-side high-frequency noise. UVLO protection is included.
4 GND power_in Chip ground reference, return for VCC and the low-side driver.
5 LO output Low-side gate-drive output. Controls the conduction/turn-off of the low-side power MOSFET, referenced to GND. Sink/source capability ±0.3 A/0.6 A.
6 VS power_in High-side floating return (switch-node reference). Connects to the source of the high-side MOSFET and the negative terminal of the bootstrap capacitor; VB is referenced to this pin. Withstands up to 550 V-600 V above GND.
7 HO output High-side gate-drive output. Controls the conduction/turn-off of the high-side power MOSFET, referenced to VS. Sink/source capability ±0.3 A/0.6 A.
8 VB power_in High-side floating bootstrap supply. Connects to the positive terminal of the bootstrap capacitor between VB and VS, charged from VCC through the bootstrap diode when VS is low. Includes UVLO protection.
