Texas Instruments TPS92612/TPS92612-Q1 High-Side LED Driver
Texas Instruments TPS92612/TPS92612-Q1 Single-Channel High-Side LED Driver operates from an automotive car battery. This device is a simple and elegant solution that delivers constant current for a single LED string. With LEDs widely used in automotive applications, simple LED drivers are becoming increasingly popular. Compared to discrete solutions, a low-cost monolithic solution lowers system-level component counts and significantly improves current accuracy and reliability. The Texas Instruments TPS92612-Q1 devices are AEC-Q100 qualified for automotive applications.
