Digital interface LED driving module reference design for automotive rear light

TIDA-020029

Design files

Overview

This reference design offers a cost-effective solution for automotive rear-light applications such as interactive tail-light clusters that can be used for vehicle-to-vehicle notifications and vehicle design personalization. This reference design incorporates two linear LED drivers. By using a controller area network (CAN) physical layer (or a local interconnect network (LIN) option), the UART-based FlexWire interface of the LED drivers easily accomplishes long-distance, off-board communication without sacrificing EMI performance.

Features
  • High pixel count
  • UART-based FlexWire interface
  • Diagnostics and protection
  • Pulse-width-modulation (PWM) dimming
  • Precise current control

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
