The DRV2667 is a digitally controlled, high-voltage driver designed to control Piezo actuators with voltages between 40 Vpp and 200 Vpp. The DRV2667 eliminates many design complexities of driving Piezo by including an integrated 105V boost converter and 200-Vpp differential output amplifier. In addition, the digital control interface ( I2C) includes real-time waveform playback, a waveform generator, and embedded RAM for waveform storage.
The Evaluation Module (EVM) kit is a complete demonstration and evaluation platform for the DRV2667. The kit includes a microcontroller, Piezo actuator, sample waveforms and capacitive touch buttons which can be used to completely demonstrate and evaluate the DRV2667.
The DRV2667 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 over the I2C port or the analog inputs.
