With LEDs being widely used in automotive applications, simple LED drivers are more and more popular. Comparing to discrete solutions, a low-cost monolithic solution lowers system-level component count and significantly improves current accuracy and reliability.

The TPS92613-Q1 device is a single-channel, high-side LED driver operating from an automotive car battery. It is a simple, yet elegant, solution to deliver constant current for a single LED string with full LED diagnostics. The one-fails–all-fail feature is able to work together with other LED drivers, such as the TPS9261x-Q1, TPS9263x-Q1, and TPS92830-Q1 devices, to address different requirements.
