U3116C 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; the recommended supply range is 5 V to 20 V, with undervoltage lockout (VCC UV+ typ. 4.5 V, UV- typ. 4.2 V). |
| 2 | HIN | input | High side driver logic input, active high; compatible with 3.3 V, 5 V and 15 V logic, with VIH minimum 2.5 V and VIL typical 1.6 V. |
| 3 | LIN | input | Low side driver logic input, active low for the U3116C (the U3115C uses an active-high LIN on this pin); logic levels follow VIH/VIL of 2.5 V and 1.6 V with VCC = 5 V to 20 V. |
| 4 | COM | power_in | Low side return; all absolute voltage parameters are referenced to COM. |
| 5 | LO | output | Low side gate drive output, swinging between 0 V and VCC. |
| 6 | VS | power_in | High side floating supply return; the high side floating supply offset voltage is rated from -5 V to 350 V. |
| 7 | HO | output | High side gate drive output, swinging between VS and VB. |
| 8 | VB | power_in | High side floating supply; VB must be held between VS + 5 V and VS + 20 V, and the absolute VB rating is -0.3 V to 365 V. |
