The UCC20225 is an isolated single input, dual-channel gate driver with 4-A source and
6-A sink peak current in a space-saving 5-mm x 5-mm LGA-13 package. It is designed to drive power
MOSFETs, IGBTs, and SiC MOSFETs up to 5-MHz 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
2.5-kVRMS reinforced isolation barrier, with a minimum of 100-V/ns
common-mode transient immunity (CMTI). Internal functional isolation between the two secondary-side
drivers allows a working voltage of up to 700-VDC.
This driver can be used for half-bridge driver with programmable dead time (DT). A
disable pin shuts down both outputs simultaneously when it is set high, and allows normal operation
when left open or grounded. As a fail-safe measure, primary-side logic failures force both outputs
The device accepts VDD supply voltages up to 25-V. A wide input VCCI range from 3-V to
18-V makes the driver suitable for interfacing with both analog and digital controllers. All the
supply voltage pins have under voltage lock-out (UVLO) protection.
With all these advanced features, the UCC20225 enables high power density, high
efficiency, and robustness in a wide variety of power applications.
