具有 8V UVLO、双输入和禁用引脚的 4A/6A、5.7kVRMS 双通道隔离式栅极驱动器 16-SOIC -40 to 125
The UCC21520 is an isolated 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-kVRMS reinforced isolation barrier, with a minimum of 100-V/ns common-mode transient immunity CM. Internal functional isolation between the two secondary-side drivers allows a working voltage of up to 1500 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 UCC21520 enables high efficiency, high power density, and robustness in a wide variety of power applications.
