EG2103 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 operating supply input with a range of 10V-20V; an external 1uF high-frequency bypass capacitor reduces high-frequency noise at this input. |
| 2 | HIN | input | High-side logic input, active high: '1' turns the high-side power MOS on and '0' turns it off, with an internal 200K pull-down so the high-side MOS is off when the input is floating. |
| 3 | LIN | input | Low-side logic input: per the truth table '0' turns the low-side power MOS on and '1' turns it off, with an internal 200K pull-down so the low-side MOS is off when the input is floating. |
| 4 | GND | power_in | Chip ground terminal. |
| 5 | LO | output | Drives the gate of the low-side power MOS; the datasheet rates output drive at 0.3A source (IO+) and 0.6A sink (IO-) for PW up to 10us. |
| 6 | VS | power_in | High-side floating ground reference, rated VB-20V to VB+0.3V in the absolute maximum table. |
| 7 | HO | output | Drives the gate of the high-side power MOS; the output is limited to VS-0.3V to VB+0.3V. |
| 8 | VB | power_in | High-side floating supply, rated up to 600V (absolute maximum -0.3V to 600V), with undervoltage shutdown at VB(off) 7.0-9.0V. |
