特長
- 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)
- Up to four different I2C addresses
説明
The DA7281 haptic driver with multiple I2C addresses combines custom drive sequences (on- and off-resonance) at up to 1kHz. The DA7281 drives both ERM and LRA (narrow and wideband) actuators and tracks resonance up to 300Hz to provide highly complex click/vibration touch effects in a wide range of applications.
The DA7281 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.
The DA7281 differs from the DA7280 and DA7282 by using two of the original trigger input pins as I2C address pins, allowing up to four DA7281 devices to be used in the same system.
Benefits
- Communicate with up to four DA7281s on the same I2C bus
- 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 the 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
