The DRV2667 device is a piezo haptic driver with integrated 105-V boost switch, integrated power diode, integrated fully-differential amplifier, and integrated digital front end capable of driving both high-voltage and low-voltage piezo haptic actuators. This versatile device supports HD haptics through the I 2C port or through the analog inputs.
The digital interface of the DRV2667 device is available through an I 2C-compatible bus. A digital interface relieves the costly processor burden of the PWM generation or additional analog channel requirements in the host system. Any writes to the internal FIFO will automatically wake up the device and begin playing the waveform after the 2-ms internal startup procedure. When the data flow stops or the FIFO under-runs, the device will automatically enter a pop-less shutdown procedure.
The DRV2667 device also includes waveform memory to store and recall waveforms with minimal latency as well as an advanced waveform synthesizer to construct complex haptic waveforms with minimal memory usage. This provide a means of hardware acceleration, relieving the host processor of haptic generation duties as well as minimizing bus traffic over the haptic interface.
The boost voltage is set using two external resistors, and the boost current limit is programmable through the R EXT resistor. A typical start-up time of 2 ms makes the DRV2667 an ideal piezo driver for fast haptic responses. Thermal overload protection prevents the device from being damaged when overdriven.
