TPS92611-Q1 Single-Channel High-Side LED Driver Texas Instruments TPS92611-Q1 Single-Channel High-Side LED Driver operates from an automotive car battery. The TPS92611-Q1 is a simple and elegant solution with LED diagnostics to deliver constant current for a single LED string. The device has a one-fails–all-fail feature that can work together with other LED drivers, such as the Texas Instruments TPS9261x-Q1, TPS9263x-Q1, and TPS9283x-Q1 devices, to address different requirements. With LEDs widely used in automotive applications, simple LED drivers are becoming more popular. Compared to discrete solutions, this low-cost monolithic solution lowers system-level component counts and significantly improves current accuracy and reliability.
