Description

This TIDA-00156 reference design is a capacitive touch / haptic feedback automotive interior lighting solution optimized for automotive Dome light / Map light applications. The solution features a haptic driver with extensive integrated library (100+ effects) for ERM actuators, constant current LED driver with integrated PWM input permitting LED brightness regulation, low power MCU optimized for capacitive touch, and LIN interface communication.

Features
  • Wide input voltage range: 12V Typical, 8-18V Continuous, 42V Load Dump
  • Low system quiescent current consumption (<100uA) handled by the on-board MSP430 putting key components in the system to sleep
  • 400 kHz buck converter switching frequency utlilized in order to stay out of the AM band
  • Design capable of supplying constant LED current and controlled LED current using a PWM signal
  • Easily accessible integrated library of waveforms via I2C communication for a variety of haptic feedback effects
  • Ability to implement cap touch detection without external components other than the on-board MSP430
