Overview
Description
The DA7280-A high-definition (HD) haptic driver combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7280-A 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-A 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.
This product is AEC-Q100 Grade 2 qualified and is perfect for being deployed in automotive applications where haptic feedback is required. DA7280-A comes in a 12-pin Wettable flank QFN (3x3mm).
Features
- 360nA idle power mode with full I2C control and memory retention
- 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
- Three methods of drive with Linux and C-like driver (HAL)
- Package: WFQFN-12 (3x3mm)
- Constant resonance frequency tracking through continuous current drive monitoring
- Ultra-low power consumption means 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 wide-band effects as well as supporting dual-resonant systems
- Drives distinct haptic effects triggered by multiple inputs without the 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 the SmartCanvas™ GUI
