3 说明

UCC5870-Q1 器件是一款高度可配置的隔离式单通道栅极驱动器，在电动汽车/混合动力汽车应用中用于驱动高功率 SiC MOSFET 和 IGBT。该器件提供功率晶体管保护，例如基于分流电阻器的过流保护、基于 NTC 的过热保护以及 DESAT 检测，还在这些故障期间提供可选的软关断或两级关断。为了进一步缩小应用尺寸，UCC5870-Q1 集成了在开关期间可用的 4A 有源米勒钳位，以及在驱动器未通电时可用的有源栅极下拉电阻。集成的 10 位 ADC 可用于监控多达六个模拟输入以及栅极驱动器温度，从而增强系统管理。集成的诊断和检测功能可简化符合 ASIL-D 标准的系统的设计。这些功能的参数和阈值可使用 SPI 接口进行配置，因此该器件几乎可与任何 SiC MOSFET 或 IGBT 一同使用。
