Automotive Basic, 4A/6A dual-channel isolated gate driver w/ enable, programmable deadtime

The UCC21331-Q1 is an

isolated dual channel gate driver family with programmable dead time and wide

temperature range. It is designed with 4A peak-source and 6A peak-sink current to

drive power MOSFET, SiC, and IGBT transistors.

The UCC21331-Q1 can be

configured as two low-side drivers, two high-side drivers, or a half-bridge driver.

The input side is isolated from the two output drivers by a 3kVRMS isolation barrier, with a

minimum of 125V/ns common-mode transient immunity (CMTI).

Protection features include: resistor

programmable dead time, disable feature to shut down both outputs simultaneously,

and integrated de-glitch filter that rejects input transients shorter than 5ns. All

supplies have UVLO protection.

With all these advanced features, the

UCC21331-Q1 device

enables high efficiency, high power density, and robustness in a wide variety of

power applications.
