7.1 Overview

The TPS92611-Q1 device is one of a family of single-channel linear LED drivers. The family provides a simple solution for automotive LED applications. Different package options in the family provide a variety of current ranges and diagnostic options. The TPS92611-Q1 device in an MSOP-8 package supports LED open-circuit detection and short-to-ground detection. A one-fails–all-fail fault bus allows the TPS92611-Q1 device to be used together with the TPS9261x-Q1, TPS9263x-Q1, and TPS9283x-Q1 families.

The output current can be set by an external R(SNS) resistor. Current flows from the supply through the R(SNS) resistor into the internal current source and to the LEDs.
