3 V at 300 mA • Diagnostics and Protection – LED Open-Circuit and Short-Circuit Detection With Auto-Recovery – Diagnostic-Enable With Adjustable Threshold for Low-Dropout Operation – Fault Bus up to 15 Devices, Configurable As Either One-Fails–All-Fail or Only-FailedChannel Off – Low Quiescent Current and Fault-Mode Current (<250 µA per Device) • Operating Junction Temperature Range: –40°C to 150°C 3 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.
