Description
General part information
UCC20520 Series
The UCC20520 is an isolated single input, dual-channel gate driver with 4-A source and 6-A sink peak current. 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.
The input side is isolated from the two output drivers by a 5.7-kVRMSreinforced 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 1500-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 low.
