Low Power High-Definition Haptic Driver for Next Generation Human Machine Interfaces

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 ap • 360nA idle power mode with full I2C control and memory retention\n• Wideband LRA driver: 25Hz to 1kHz with resonant mode\n• Frequency tracking support up to 300Hz\n• Low-latency direct drive for haptics\n• On-the-fly diagnostics\n• Custom waveform sequences\n• Three methods of drive with Linux and;
