Ultra-Low Power, Wide-Bandwidth Haptic Driver

The DA7282 ultra-low power haptic driver, combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7282 drives both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz producing highly complex click/vibration touch effects in a wide range of applications.

The DA7282 differs from the DA7280 and DA7281 by providing the capability to go into a full standby mode, lowering current consumption to 5nA.

Benefits

* 20x lower standby current, minimizing the drain on small battery systems * Constant resonance frequency tracking through continuous current drive monitoring * Ultra-low power consumption meaning 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 wideband effects as well as supporting dual-resonant systems * Drives distinct haptic effects triggered by multiple inputs without need to wake the host processor * Detects issues with motor automatically * Frequency, time, amplitude triplets to program the waveform * Quick and easy software development using the SmartCanvas™ GUI
