UCC21520 UCC2151的区别是什么

请问UCC21520 UCC2151的有什么区别

Johnsin Tao:

Hi:

   使能控制上的差异。

   You are correct that the only difference between the UCC21520 and the UCC21521 is in Pin#5. This is Disable on UCC21520 and Enable on UCC21521. We made these separate parts in order to satisfy the needs of our customers. Some prefer an Enable High function, others prefer a Disable High function. This necessitates a different part number to avoid confusion between the parts.
