4-A, 6-A, 2.5-kVRMS Isolated Dual-Channel Gate Driver in LGA - UCC21225A

UCC21225A (ACTIVE)

4-A, 6-A, 2.5-kVRMS Isolated Dual-Channel Gate Driver in LGA

 

Description

The UCC21225A is an isolated 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 configured as two low-side drivers, two high-side drivers, 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. As a fail-safe measure, primary-side logic failures force both outputs low.

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.
