DA7282中文资料Ultra-Low Power, Wide-Bandwidth Haptic Driver数据手册Renesas规格书

描述 Description

The DA7282 ultra-low power haptic driver, combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7282 drives both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz 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 5nA.

Benefits20x lower standby current, minimizing the drain on small battery systemsConstant resonance frequency tracking through continuous current drive monitoringUltra-low power consumption meaning 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 wideband effects as well as supporting dual-resonant systemsDrives distinct haptic effects triggered by multiple inputs without need to wake the host processorDetects issues with motor automaticallyFrequency, time, amplitude triplets to program the waveformQuick and easy software development using the SmartCanvas™ GUI
