Description
General part information
UCC21231 Series
The UCC21231 is an isolated dual-channel gate driver family with programmable dead time and wide temperature range. This device exhibits consistent performance and robustness under extreme temperature conditions. UCC21231 is designed with 4A peak-source and 6A peak-sink current to drive power MOSFET, and GaN transistors.
The UCC21231 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 1.6kVRMS isolation barrier, with a minimum of 125V/ns common-mode transient immunity (CMTI).
Protection features include: resistor programmable dead time, enable feature to shut down both outputs simultaneously, integrated de-glitch filter that rejects input transients shorter than 5ns, and negative voltage handling for up to –2V spikes for 200ns on input and output pins. All supplies have UVLO protection.
