Description for the UCC21520

The UCC21520 and the UCC21520A areisolated dual-channel gate drivers with 4-A source and 6-A sinkpeak current. It is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5-MHz withbest-in-class propagation delay and pulse-width distortion.

The input side is isolated from the two output drivers by a5.7-kVRMS reinforced isolation barrier, with a minimum of 100-V/nscommon-mode transient immunity (CMTI). Internal functional isolation between the two secondary-sidedrivers allows a working voltage of up to 1500 VDC.

Every driver can be configured as two low-side drivers, two high-sidedrivers, or a half-bridge driver with programmable dead time (DT). A disable pin shuts down bothoutputs simultaneously when it is set high, and allows normaloperation when left open or grounded. As a fail-safe measure, primary-side logic failures forceboth outputs low.

Each device accepts VDD supply voltages up to 25 V. A wide input VCCI rangefrom 3 V to 18 V makes the driver suitable for interfacing with both analog and digitalcontrollers. All the supply voltage pins have under voltage lock-out(UVLO) protection.

With all these advanced features, the UCC21520 and the UCC21520A enable high efficiency, high powerdensity, and robustness in a wide variety of power applications.
