U3115E

UNI SEMIC · Gate Drivers · SOP-8

U3115E 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 range 9 V to 20 V (absolute maximum 20 V).
2 HIN input High side driver logic input, active high; logic input range is 0 to VCC and it accepts 3.3 V, 5 V and 15 V logic.
3 LIN input Low side driver logic input, described in the datasheet as active low; logic input range is 0 to VCC.
4 COM power_in Low side return; all voltage parameters in the datasheet are referenced to COM.
5 LO output Low side gate drive output, swinging between 0 and VCC in recommended conditions.
6 VS power_in High side floating supply return; recommended offset voltage range is -5 V to 350 V, with an allowable dVS/dt transient of 55 V/ns maximum.
7 HO output High side gate drive output referenced to VS, with output voltage between VS and VB.
8 VB power_in High side floating supply; recommended VB is VS + 9 V to VS + 20 V (absolute maximum 365 V); the part has an integrated bootstrap diode.

CAD (KiCad official)

  • Symbol: U3115E
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: u3115e-etched.step / u3115e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); u3115e.step / u3115e.glb are the bare package body.
