Other Parts Discussed in Thread: UCC21750
I want to evaluate DESAT operation of UCC21750 using EVM board.
In the userguide of UCC217xx Family, Part 2.2.3 Overcurrent and short circuit soft Turn OFF Test session(Page13), it is mentioned that "For UCC21750 there is no need to connect channel B (Ch.2) of function generator.:.
To evaluate DESAT operation,I thought, I should give voltage more than 9V (DESAT threshold), but it seems not according to userguide description.
I want to know why ther is no need to give function on pin DESAT.
