Product Overview

The DRV8662EVM is an evaluation module for DRV8662. The DRV8662 is a fully differential, high voltage piezo actuator driver that provides quick response time for single layer and multi layer piezo actuators. The DRV8662 drives piezo loads up to 200V differentially using an adjustable integrated boost converter. The evaluation module contains the DRV8662 piezo haptics driver, a programmable MSP430, and passive components for complete evaluation. The DRV8662 is a single chip piezo haptic driver with integrated 105V boost switch, integrated power diode, and integrated fully differential amplifier. This versatile device is capable of driving both high voltage and low voltage piezo haptic actuators. The input signal can be either differential or single ended. The DRV8662 supports four GPIO controlled gains 28.8dB, 34.8dB, 38.4dB, and 40.7dB.
