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.

The UCC21231 device accepts VDD supply voltages up to 25V. An input VCCI range from 3V to 5.5V makes the driver suitable for interfacing with digital controllers. All supply voltage pins have undervoltage lock-out (UVLO) protection.

With all these advanced features, the UCC21231 device enables high efficiency, high power density, and robustness in a wide variety of power applications.
