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.

DA7280将极低的空闲电流消耗（360nA）与低延迟触发器输入相结合，以在应用程序进程处于深度睡眠状态时最大限度地减少按下按钮后的延迟。

Features

  • 360nA空闲功率模式，带全I2C control and memory retention
  • 宽带LRA驱动器：25Hz至1kHz，谐振模式
  • Frequency tracking support up to 300Hz
  • Low-latency direct drive for haptics
  • On-the-fly diagnostics
  • 自定义波形序列
  • Linux和类C驱动程序（HAL）的三种驱动方法

Benefits

  • 基于连续电流驱动监测的恒谐振频率跟踪
  • Ultra-low power consumption means longer battery life
  • Only 0.75ms latency when responding from ultra-low power state
  • 驱动LRA关闭共振以实现自定义效果，或驱动双共振系统以实现二维振动
  • 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
