Description

Description
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 I2C port or through the analog inputs.
The digital interface of the DRV2667 device is available through an I2C-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.
