Texas Instruments DRV2665 Piezo Haptic Driver
Texas Instruments DRV2665 is a piezo haptic driver with integrated 105V boost switch, integrated power diode, integrated fully-differential amplifier, and integrated digital front end. This versatile TI device is capable of driving both high-voltage and low-voltage piezo haptic actuators. The input signal of the DRV2665 can be driven as haptic packets over the I²C port or via the analog inputs. The DRV2665 digital interface is available via an I²C compatible bus. A digital interface relieves the costly processor burden of 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 2ms internal start-up procedure. This TI piezo haptic driver is ideal for use in mobile phones, tablets, touch-enabled devices, and more.
