UCC27201ADR

Texas Instruments · Gate Drivers · SOIC-8

UCC27201ADR 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 voltage input to lower gate driver (8V to 17V recommended); decouple to VSS with 0.22μF to 1.0μF capacitor.
2 HB power_in High-side bootstrap supply input; external bootstrap capacitor (0.022μF to 0.1μF) required between HB and HS; voltage range VHS + 8V to VHS + 17V or VDD - 1V to 115V maximum.
3 HO output High-side gate driver output; drives high-side MOSFET gate with 3A peak source/sink capability and 22ns typical propagation delay.
4 HS input High-side source reference node; connects to source of high-side MOSFET; rated -18V (repetitive pulse) to 120V DC.
5 HI input High-side gate driver input; TTL-compatible with rising threshold 1.9V-2.7V (2.3V typical) and falling threshold 1.3V-1.9V (1.6V typical), 0.7V hysteresis.
6 LI input Low-side gate driver input; TTL-compatible with rising threshold 1.9V-2.7V (2.3V typical) and falling threshold 1.3V-1.9V (1.6V typical), 0.7V hysteresis.
7 VSS power_in Negative supply terminal and ground reference for the device; return path for all gate driver output currents.
8 LO output Low-side gate driver output; drives low-side MOSFET gate with 3A peak source/sink capability and 22ns typical propagation delay.
