Other Parts Discussed in Thread: UCC28C43, UC1843A
Hi Team,
I have an issue with UCC28C43-EP. It burns out in our design after low temperature test( -40 celsium). I'm trying to find out why.
I've attached the part of the schematic and PCB layout. Could you look at that? May be there is some mistake in the IC connection.
We keep our device in the frozen camera during 2 hours at -40 С, then turn the device on. As a result UCC28C43-EP has a short circuit between VDD and GND.
Note. The Device is the Brake Supply Board. Device supplys the electromagnetic brake in the electromechanical actuator.
