Ultra-Low-Power, Wide-Bandwidth Haptic Driver

DA7282超低功率触觉司机,结合custom drive sequences, on- and off-resonance, at up to 1 kHz. The DA7282 drives both ERM and LRA (narrow and wideband) actuators and track resonance up to 300 Hz 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 5 nA.

Features

  • 5 NA备用电流消耗
  • Wideband LRA driver: 25 Hz to 1 kHz with resonant mode
  • Frequency tracking support up to 300 Hz
  • 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

  • 20x lower standby current, minimizing the drain on small battery systems
  • 通过连续电流驱动监控恒定谐振频率跟踪
  • Ultra-low power consumption meaning longer battery life
  • Only 0.75 ms 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 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 Dialog’s SmartCavas™ GUI

Evaluation support

The Dialog SmartCanvas™ advanced GUI tool can be used in conjunction with the DA7282 evaluation board to enable quick and easy configuration of the DA7282 along with a connected LRA or ERM. TheDA7282 evaluation kit is flexible enough to be used stand alone or wired into an existing customer application allowing it to be used to evaluate, design, and fine-tune haptic sequences easing system integration.
