The DRV2665 device is a piezo haptic driver with integrated 105-V boost switch, integrated power diode, integrated fully-differential amplifier, and integrated digital front end. This versatile device is capable of driving both high-voltage and low-voltage piezo haptic actuators. The input signal can be driven as haptic packets over the I 2C port or through the analog inputs.

The digital interface of the DRV2665 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 first-in, first-out buffer (FIFO) will automatically wake up the device and begin playing the waveform after the 2 ms internal start-up procedure. When the data flow stops or the FIFO under-runs, the DRV2665 device will automatically enter a pop-less shutdown procedure.

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 DRV2665 device an ideal piezo driver for fast haptic responses. Thermal overload protection prevents the device from being damaged when overdriven.
