DA7280数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

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.

BenefitsConstant resonance frequency tracking through continuous current drive monitoringUltra-low power consumption means longer battery lifeOnly 0.75ms latency when responding from ultra-low power stateDrives LRAs off-resonance for custom effects, or dual-resonant systems for two-dimensional vibrationEnables wide-band effects as well as supporting dual-resonant systemsDrives distinct haptic effects triggered by multiple inputs without the need to wake the apps processorDetects issues with motor automaticallyFrequency, time, amplitude triplets to program the waveformQuick and easy software development using the SmartCanvas™ GUI
