LP8860-Q1 Electrical Overstress Analysis and Recommendation

 

The LP8860-Q1 is an automotive high-efficiency LED driver that has boost controller and four highprecision current sinks. Clean silicon is expected to perform as specified by the LP8860-Q1 data sheet when operated under normal operation. There are several root causes that could potentially be associated to electrical overstress (EOS) damage inherent to integrated circuits. This application report discusses some details about models, examples, solutions, and best practices associated to EOS damage induced by external applications and procedures using LP8860-Q1.
