UCC27201AD

Texas Instruments · Gate Drivers · SOIC-8

UCC27201AD from Texas Instruments, in a SOIC-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 VDD power_in Positive supply for lower gate driver; decouple with 0.22μF to 1.0μF capacitor to VSS.
2 HB power_in High-side bootstrap supply with on-chip diode; external capacitor (0.022μF to 0.1μF typical) positive terminal connects here.
3 HO output High-side gate driver output; connect to high-side MOSFET gate.
4 HS input High-side source reference; connect to high-side MOSFET source and bootstrap capacitor negative terminal.
5 HI input High-side input control signal.
6 LI input Low-side input control signal.
7 VSS power_in Negative supply terminal and ground reference for the device.
8 LO output Low-side gate driver output; connect to low-side MOSFET gate.
