Descripción de UCC21520
The UCC21520 is an isolated dual-channel gate driver with 4A source and 6A sink peak current. It is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5MHz.
The input side is isolated from the two output drivers by a 5.7kVRMS reinforced isolation barrier, with a minimum of 125V/ns common-mode transient immunity (CMTI). Internal functional isolation between the two secondary-side drivers allows a working voltage of up to 1500VDC.
Every 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.
Each device accepts VDD supply voltages up to 25V. A wide input VCCI range from 3V to 18V makes the driver suitable for interfacing with both analog and digital controllers. All supply voltage pins have under voltage lock-out (UVLO) protection.
With all these advanced features, the UCC21520 enables high efficiency, high power density, and robustness.
