The UCC21551x-Q1 is an isolated dual channel gate driver family with programmable dead time and wide temperature range. The device is designed with 4A peak-source and 6A peak-sink current to drive power MOSFET, SiC, and IGBT transistors.
The UCC21551x-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 5kVRMS isolation barrier, with a minimum of 125V/ns common-mode transient immunity (CMTI). DFJ28 package offers >5.3mm CH-to-CH creepage to support high voltage systems.
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-Q1 device enables high efficiency, high power density, and robustness in a wide variety of power applications.
