3 说明

UCC20520 是一款隔离式单输入、双通道栅极驱动器，其峰值拉电流为 4A，峰值灌电流为 6A。该器件设计用于驱动高达 5MHz 的功率 MOSFET、IGBT 和 SiC MOSFET，具有一流的传播延迟和脉宽失真度。

输入侧通过 5.7kVRMS 增强型隔离层与两个输出驱动器隔离，具有最少100V/ns的共模瞬态抗扰度 (CMTI) 。两个次级侧驱动器之间的内部功能隔离，支持的工作电压高达 1500 VDC。

该驱动器可用于具有可编程死区时间 (DT) 的半桥驱动器。禁用引脚在设为高电平时可同时关断两个输出，并在开路或接地时允许正常运行。作为一种故障安全措施，初级侧逻辑故障强制两个输出均为低电平。

此器件接受高达 25V 的 VDD 电源电压。3V 到 18V 的宽输入电压 VCCI 范围使得该驱动器适用于与模拟和数字控制器连接。所有电源电压引脚都具有欠压锁定 (UVLO) 保护功能。

凭借所有这些高级特性，UCC20520 能够在各种各样的电源应用中实现高效率、高电源密度和稳健性。
