The UCC20225-Q1 is a single-input, dual-output isolated gate driver with 4-A source and6-A sink peak current in 5-mm x 5-mm LGA-13. It is designed to drive power transistors up to 5-MHzwith best-in-class propagation delay and pulse-width distortion.

The input side is isolated from the two output drivers by a2.5-kVRMS 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-VDC.

The UCC20225-Q1 allows programmable dead time (DT) througha resistor on DT pin. A disable pin shuts down both outputs simultaneously when it is set high, andallows normal operation when left open or grounded.

The device accepts VDD supply voltages up to 25-V. A wide VCCI range from 3-V to 18-Vmakes the driver suitable for interfacing with both analog and digital controllers. All supplyvoltage pins have under voltage lock-out (UVLO) protection.

With all these advanced features, the UCC20225-Q1 enableshigh power density, high efficiency, and robustness in a varietyof automotive applications.
