DA7280
Low-power high-definition Haptic Driver for next generation human-machine interfaces

Low-power, wide-bandwidth Haptic Driver
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.
Features
360nA idle power mode with full I2C control and memory retention
Wideband LRA driver: 25Hz to 1kHz with resonant mode
Frequency tracking support up to 300Hz
Low-latency direct drive for haptics
On-the-fly diagnostics
Custom waveform sequences
Three methods of drive with Linux and C-like driver (HAL)
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 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 Dialog’s SmartCavas™ GUI

Evaluation support
The Dialog SmartCanvas™ GUI in conjunction with the DA7280 performance evaluation board enables quick and easy evaluation of the DA7280 along with the chosen LRA or ERM. With the attached 100g mass and an analog accelerometer the board is used to evaluate, design, and fine-tune your haptic sequences.
