UCC20225 - 4-A, 6-A, 2.5-kVRMS Isolated Dual-Channel Gate Driver With Single Input in LGA

The UCC20225 is an isolated single input, dual-output gate driver with 4-A source and 6-Asink peak current in a 5-mm x 5-mm LGA-13 package. It is designed to drive power transistors up to5-MHz with best-in-class propagation delay and pulse-width distortion.

The input side is isolated from the two output drivers by a2.5-kV_RMS isolation barrier, with minimum 100-V/ns common-mode transientimmunity (CMTI). Internal functional isolation between the two output-side drivers allows workingvoltage up to 700-V_DC.

The UCC20225 allows programmable dead time (DT) through a resistor on DT pin. A disablepin shuts down both outputs simultaneously when it is set high, and allows normal operation whenleft open or grounded.

The device accepts VDD supply voltages up to 25-V. A wide input VCCI range from 3-V to18-V makes the driver suitable for interfacing with both analog and digital controllers. All thesupply voltage pins have under voltage lock-out (UVLO) protection.

With all these advanced features, the UCC20225 enables high power density, highefficiency, and robustness in a wide variety of power applications.
