U3115C from UNI SEMIC, 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 | Low side and logic fixed supply; recommended operating range is 5 V to 20 V. |
| 2 | HIN | input | High side driver logic input (active high), compatible with standard CMOS or LSTTL outputs down to 3.3 V logic. |
| 3 | LIN | input | Low side driver logic input, specified in the datasheet as active low. |
| 4 | COM | power_in | Low side return; all voltage parameters are referenced to COM. |
| 5 | LO | output | Low side gate drive output, driven by a high pulse current buffer stage designed for minimum cross-conduction. |
| 6 | VS | power_in | High side floating supply return; offset voltage rated from -6 V (logic operational) to 350 V in recommended conditions. |
| 7 | HO | output | High side gate drive output for driving an N-channel power MOSFET or IGBT in the high side configuration. |
| 8 | VB | power_in | High side floating supply; recommended VB is VS + 5 V to VS + 20 V. |
