EG2108 from EG Micro, in a SOIC-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, 10V-20V range, with a 1uF high-frequency bypass capacitor recommended to reduce input noise. |
| 2 | HIN | input | Active-high logic input controlling the high-side power MOSFET (0 = off, 1 = on), with internal 200K pull-down. |
| 3 | LIN | input | Active-high logic input controlling the low-side power MOSFET (0 = off, 1 = on), with internal 200K pull-down. |
| 4 | GND | power_in | Chip ground. |
| 5 | LO | output | Output driving the low-side power MOSFET gate, with 0.3A source / 0.6A sink capability. |
| 6 | VS | power_in | High-side floating ground (return), allowed from VB-20V to VB+0.3V. |
| 7 | HO | output | Output driving the high-side power MOSFET gate, with 0.3A source / 0.6A sink capability. |
| 8 | VB | power_in | High-side floating supply, absolute maximum 600V, bootstrapped via external diode and capacitor. |
