The DRV8662 drives piezo loads up to 200 V differentially using an adjustable 100V integrated boost converter. The evaluation module contains the DRV8662RGP piezo haptics driver, a programmable MSP430, and passive components for complete evaluation. This document contains the EVM schematic, PCB, and BOM as well as instructions for operating the EVM. 图 评估模块外形图 DRV8662EVM 评估 模 块 主 要特 性 :• High-voltage haptics driver• Drives single-layer and multi-
