EG2131 from EG Micro, in a SOP-8-150mil. 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 | VCC | power_in | Low-side supply input, 11V-20V operating range. Bypass with a 0.1uF high-frequency capacitor close to the pin to attenuate supply noise. |
| 2 | HIN | input | High-side logic input, active-high. '1' turns the high-side power MOSFET on, '0' turns it off. Internal 200k pull-down to GND ensures the high-side output stays off when the pin floats. |
| 3 | LIN | input | Low-side logic input, active-low (inverted). '0' turns the low-side power MOSFET on, '1' turns it off. Internal 200k pull-up to +5V holds the low-side output off when the pin floats. |
| 4 | GND | power_in | Device ground reference for VCC and the low-side driver return. |
| 5 | LO | output | Low-side gate drive output. Drives the gate of the low-side power MOSFET/IGBT referenced to GND with ±1A/1.5A source/sink capability. |
| 6 | VS | power_in | High-side floating return / switch-node reference. Connects to the source of the high-side MOSFET (or emitter of the IGBT) and is the negative rail for the bootstrap capacitor. |
| 7 | HO | output | High-side gate drive output. Drives the gate of the high-side power MOSFET/IGBT referenced to VS with ±1A/1.5A source/sink capability. Can swing up to 300V above GND. |
| 8 | VB | power_in | High-side floating bootstrap supply. Connect a bootstrap capacitor from VB to VS and a bootstrap diode from VCC to VB. Rated for up to ~300V above GND. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 361 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
