3 Description
With LEDs being widely used in automotive applications, simple LED drivers are more and more popular. paring to discrete solutions, a low-cost monolithic solution lowers system-level ponent count and significantly improves current accuracy and reliability.
The TPS92613-Q1 device is a single-channel, highside 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...
