UCC21750QDWEVM-025: UCC21750QDWEVM-025

Part Number: UCC21750QDWEVM-025
Other Parts Discussed in Thread: UCC21750, UCC21710
  1. 您好,我在使用UCC21750QDWEVM-025进行输入输出开关测试时,为什么需要将TP7与source极进行链接?
  2. 对UCC21750进行OC功能测试时,为什么要将IN+ pin与EN pin链接在一起,能详细描述一下触发时序吗?UCC21750为什么不像UCC21710一样使用CS 触发短路?
  3. 对UCC21750的OC功能进行测试,发现Desat阈值电压不超过7.27V,并不是datasheet中的9V,软关断时间tDESATFIL=2.43us,远大于datasheet给出的时间标准230ns,请问我该如何排查?
