Other Parts Discussed in Thread: UCC27524A
Hi, my design contains an uncommon condition, so that I want to confirm with the designer of this chip. The driver power supply VDD sometimes will disappear firstly, and in the mean time the 5V LI or HI PWM input is still there, which means when VDD=0V and LI/HI=5V, obviously this violates the spec in the table below, could you explain if this is really an issue I need to worry about. Another point here, when VDD lowers than 6.5V, the chip already in UVLO status, I can't make the decision without knowing the details of the internal structure. Thank you.
