Low Power High-Definition Haptic Driver for Next Generation Human Machine Interfaces

The DA7280 high-definition (HD) haptic driver combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7280 can drive both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz to drive the most complex click/vibration touch effects in a wide range of applications.

The DA7280 combines very low idle current consumption (360nA) with low-latency trigger inputs to minimize the delay after button presses when an application process is in deep sleep.

Benefits

* Constant resonance frequency tracking through continuous current drive monitoring * Ultra-low power consumption means longer battery life * Only 0.75ms latency when responding from ultra-low power state * Drives LRAs off-resonance for custom effects, or dual-resonant systems for two-dimensional vibration * Enables wide-band effects as well as supporting dual-resonant systems * Drives distinct haptic effects triggered by multiple inputs without the need to wake the apps processor * Detects issues with motor automatically * Frequency, time, amplitude triplets to program the waveform * Quick and easy software development using the SmartCanvas™ GUI
