Texas Instruments UCC20225/UCC20225-Q1 Isolated Gate Drivers

Texas Instruments UCC20225/UCC20225-Q1 Isolated Gate Drivers are single-input, dual-channel gate drivers with 4A source and 6A sink peak current. This driver comes in a space-saving 5mm x 5mm LGA-13 package. This device is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5MHz with best-in-class propagation delay and pulse-width distortion, in applications requiring the highest power density. The input side is isolated from the two output drivers by a 2.5kVRMS reinforced isolation barrier, with a minimum of 100V/ns common-mode transient immunity (CMTI). Internal functional isolation between the two secondary-side drivers allows a working voltage of up to 700VDC.

The UCC20225/UCC20225-Q1 can be used for a half-bridge driver with programmable dead time (DT). When set high, a disable pin shuts down both outputs simultaneously and allows normal operation when left open or grounded. As a fail-safe measure, primary-side logic failures force both outputs low. The Texas Instruments UCC20225-Q1 devices are AEC-Q100 qualified for automotive applications.
