UCC27201DR

Texas Instruments · Gate Drivers · SOIC-8

UCC27201DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply to the lower gate driver; decouple to VSS with 0.22μF to 1μF capacitor.
2 HB power_in High-side bootstrap supply; connect positive terminal of bootstrap capacitor (0.022μF to 0.1μF) to this pin.
3 HO output High-side output; connect to the gate of the high-side power MOSFET.
4 HS input High-side source connection; connect to source of high-side power MOSFET and bootstrap capacitor negative terminal.
5 HI input High-side input.
6 LI input Low-side input.
7 VSS power_in Negative supply terminal for the device, generally grounded.
8 LO output Low-side output; connect to the gate of the low-side power MOSFET.
