说明

是UCC20225-Q1 系列是一款单输入、双输出隔离式栅极驱动器,具有 4A 峰值拉电流和 6A 峰值灌电流,并且采用 5mm x 5mm LGA-13 封装。该器件旨在以一流的传播延迟和脉宽失真度驱动功率晶体管,频率最高可达 5MHz。

输入侧通过一个 2.5kVRMS 隔离栅与两个输出驱动器隔离,共模瞬态抗扰度 (CMTI) 的最小值为 100V/ns。两个输出侧驱动器之间的内部功能隔离支持高达 700VDC 的工作电压。

UCC20225-Q1 系列通过 DT 引脚上的电阻器支持可编程死区时间。DIS 引脚在设为高电平时可同时关断两个输出,在接地时允许器件正常运行。

该器件接受的 VDD 电源电压高达 25V。凭借 3V 至 18V 的宽 VCCI 范围,该驱动器非常适合连接模拟和数字控制器。所有电源电压引脚都具有欠压锁定 (UVLO) 保护功能。

凭借上述所有高级 功能,UCC20225-Q1 系列可在各种汽车 应用中实现高功率密度、高效率和稳健性。
