open-in-new Find other Automotive LED drivers

Description

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

The TPS92611-Q1 device is a simple single-channel high-side LED driver operating from an automotive car battery. It is a simple and elegant solution, with LED diagnostics, to deliver constant current for a single LED string. Its one-fails–all-fail feature is able to work together with other LED drivers, such as the TPS9261x-Q1, TPS9263x-Q1, and TPS9283x-Q1 devices, to address different requirements.
