Overview
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.
Benefits
- 20x lower standby current, minimizing the drain on small battery systems
- Constant resonance frequency tracking through continuous current drive monitoring
- Ultra-low power consumption meaning longer battery life
- Only 0.75ms latency when responding from ultra-low power state
- Drives LRAs off-resonance for custom effects, or dual-resonant systems for two-dimensional vibration
- 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 the SmartCanvas™ GUI
Features
- 5nA standby current consumption
- Wideband LRA driver: 25Hz to 1kHz with resonant mode
- Frequency tracking support up to 300Hz
- Low-latency direct drive for haptics
- On-the-fly diagnostics
- Custom waveform sequences
