The UCC21551x 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 UCC21551x 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 5kVRMS 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 UCC21551x device enables high efficiency, high power density, and robustness in a wide variety of power applications.
