3 说明

UCC21220 和 UCC21220A 器件是具有 4A 峰值拉电流和 6A 峰值灌电流的基本隔离式和功能隔离式双通道栅极驱动器。它们设计用于在 PFC、隔离式直流/直流和同步整流应用中驱动功率 MOSFET 和 GaNFET，借助超过 100V/ns 的共模瞬态抗扰度 (CMTI)，可实现快速开关性能和稳健的接地反弹保护。

这些器件可以配置为两个低侧驱动器、两个高侧驱动器或半桥驱动器。可以将两个输出并联，以形成单个驱动器，由于具有一流的延迟匹配性能，因此可以在重负载条件下使驱动强度加倍。

保护特性包括以下几项：DIS 引脚在设置为高电平时可同时关断两个输出；INA/B 引脚可抑制短于 5ns 的输入瞬态；输入和输出可以承受 –2V 的尖峰达 200ns，所有电源都具有欠压锁定 (UVLO) 功能，有源下拉保护功能可以在断电或悬空时将输出钳制在 2.1V 以下。

凭借这些特性，这些器件可以在各种电源应用中实现高效率、高功率密度和稳健性。
