描述

The DA7280-A high-definition (HD) haptic driver combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7280-A 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-A 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.

This product is AEC-Q100 Grade 2 qualified and is perfect for being deployed in automotive applications where haptic feedback is required. DA7280-A comes in a 12-pin Wettable flank QFN (3x3mm).

特性

  • 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)
  • Package: WFQFN-12 (3x3mm)
  • 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
