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将非常低的空闲电流消耗（360NA）与低延迟触发输入相结合，以最小化按钮后按钮后的延迟，当应用过程深度睡眠时。

Features

  • 360NA空闲电源模式完整I2C control and memory retention
  • 宽带LRA驱动器：25Hz至1KHz，具有共振模式
  • Frequency tracking support up to 300Hz
  • Low-latency direct drive for haptics
  • On-the-fly diagnostics
  • 自定义波形序列
  • 用Linux和C样驱动器（HAL）驱动的三种方法

Benefits

  • 通过连续电流驱动监控恒定谐振频率跟踪
  • Ultra-low power consumption means longer battery life
  • Only 0.75ms latency when responding from ultra-low power state
  • 驱动LRA的自定义效应，或用于二维振动的双谐振系统
  • 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
