Advanced haptic driver simplifies tactile feedback design in consumer and industrial


Design files


This haptic driver reference design for LRA and ERM motors helps eliminate the design complexities of haptic motor control with features like reduced solution size, high efficiency output drive, closed-loop motor control, quick device startup and auto-resonance frequency tracking. This reference design board can be used for developing, testing and demonstrating motor-based haptic effects for systems with capacitive touch buttons and other interfaces. It also provides an easy way to compare ERM and LRA haptic effects.

  • Preconfigured capacitive touch and haptic feedback demonstration/evaluation system
  • Easy start up within minutes
  • Includes both ERM and LRA haptic actuators for easy comparison
  • Supports custom-designed waveforms and external actuators for prototyping and development
