EG2104D 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 | VCC | power_in | Chip supply input, specified at 9V to 25V; a high-frequency 0.1uF bypass capacitor is recommended to reduce high-frequency noise at the supply pin. |
| 2 | IN | input | Logic input controlling the high-side and low-side MOSFET outputs: IN=1 drives HO high and LO low, IN=0 drives LO high and HO low; logic high threshold is 2.5V minimum and low threshold is 1.0V maximum, with an internal 200K pull-down. |
| 3 | SD | input | Active-low shutdown logic input: when SD is 0 both LO and HO are forced low, and when SD is 1 the outputs follow IN; an internal 200K pull-down is included. |
| 4 | GND | power_in | Chip ground reference terminal. |
| 5 | LO | output | Output driving the low-side N-channel MOSFET gate, rated at 0.3A source and 0.6A sink current. |
| 6 | VS | power_in | High-side floating ground reference that connects to the high-side MOSFET source; the datasheet lists the VS voltage range as VB-25V to VB+0.3V. |
| 7 | HO | output | Output driving the high-side N-channel MOSFET gate, referenced to VS, rated at 0.3A source and 0.6A sink current. |
| 8 | VB | power_in | High-side floating supply for the bootstrap circuit; the VB undervoltage lockout turns on at 7.0V typical and turns off at 6.5V typical, with absolute maximum rating of 600V. |
