UC3845A: Failure modes for PWM Controller

Samir,

You can enter any TI orderable part number (OPN) here and obtain the Quality, Reliability & Packaging report. From the link I am providing, attached is an example report I ran on UC3845A. Additionally I've attached the UCx84xA Functional Safety FIT Rate, FMD and Pin FMA report. This report covers the failure effects for open and shorted pins to GND and shorted adjacent pins to each other.

Regards,

Steve M
