The UCC21225A is an isolated dual-channel gate driver with 4-A source and 6-A sink peak
current in a 5-mm x 5-mm LGA-13 package. It is designed to drive power transistors up to 5-MHz with
best-in-class propagation delay and pulse-width distortion.
The input side is isolated from the two output drivers by a
2.5-kVRMS isolation barrier, with 100-V/ns minimum common-mode transient
immunity (CMTI). Internal functional isolation between the two secondary side drivers allows
working voltage up to 700-VDC.
This driver can be configured as two low-side, two high-side, or a 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.
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 UCC21225A enables high power density, high
efficiency, and robustness in a wide variety of power applications.
