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.

Features:

  • High-Voltage Piezo Haptic Driver

  • Drives single-layer and multi-layer piezo actuators

  • Adjustable 200V Differential Output

  • A programmable MSP430 with sample waveforms

  • Directly connect external PWM and analog signals

  • Fast Start-up Time of 1.5ms

  • Wide Supply Voltage Range of 3.0V to 5.5V

  • 1.8V Compatible Digital Pins

  • Thermal Protection
