EG2185 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 | HIN | input | High-side logic input, active high: a logic 1 turns the high-side MOSFET on and a logic 0 turns it off, with an internal 250 kΩ pull-down on this input. |
| 2 | LIN | input | Low-side logic input, active low: a logic 0 turns the low-side MOSFET on and a logic 1 turns it off, with an internal pull-up to 5 V that keeps both outputs off when the input is floating. |
| 3 | GND | power_in | Chip ground terminal. |
| 4 | LO | output | Low-side gate driver output that switches the low-side power MOSFET, rated at 4 A peak source and sink current (IO+/- 4 A). |
| 5 | VCC | power_in | Chip supply input rated 10 V to 20 V; a 0.1 µF high-frequency bypass capacitor close to the pin is recommended to reduce high-frequency noise. |
| 6 | VS | power_in | High-side floating ground reference, the return for the high-side drive; absolute limits are VB-20 V to VB+0.3 V. |
| 7 | HO | output | High-side gate driver output that switches the high-side power MOSFET, referenced to VS and limited to VB+0.3 V. |
| 8 | VB | power_in | High-side floating bootstrap supply, rated up to 600 V absolute maximum (-0.3 V to 600 V) relative to ground. |
