Automotive Auto-Dimming Mirror Reference Design for Electrochromic Mirrors

TIDA-01539

Design files

Overview

Modern vehicles utilize auto-dimming mirrors to prevent glare and visibility loss for the driver. This reference design utilizes modern human-eye-response ambient light sensors and a high-current amplifier stage to drive a capacitive electrochromic mirror load.

Features
  • Human-eye-response light sensors
  • 10-bit output
  • 3.3V, 400mA capacitive load driver
  • Fast discharge of electrochromic load
  • Wide VBAT operation (up to 40V)

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