DRV8662EVM: 50 ~ 200V Piezo Haptic Driver
Summary
The DRV8662EVM Evaluation Module (EVM) 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.
