Overview

The TPS92611QDGNRQ1 is an automotive-grade, AEC-Q100 qualified single-channel linear LED driver designed to provide a constant current output for automotive lighting applications. It operates from a wide input voltage range and features high-side current sensing with integrated protection mechanisms to ensure reliable operation in harsh vehicle environments.

Why Choose This Part

The device features an integrated PWM dimming interface and diagnostic outputs for detecting open or shorted LED strings. Its linear architecture eliminates electromagnetic interference (EMI) concerns typically associated with switching regulators, while the small MSOP-8 PowerPAD package provides excellent thermal dissipation.

Applications

Automotive Rear Lamps
Ideal for tail lights, stop lights, and turn signals where constant current is required for consistent brightness.
Interior Lighting
Provides precise current control for cabin overhead lights, ambient lighting, and glove box illumination.
CHMSL
Efficiently drives Center High-Mount Stop Lamps with minimal external components.

Getting Started

Engineers can evaluate this part using the TPS92611EVM evaluation module from Texas Instruments. Design involves selecting a single external sense resistor to set the regulated output current and connecting the PWM pin to a microcontroller for brightness control.
