The DRV2700RGPR is a versatile, high-voltage piezo driver integrated circuit (IC) designed by Texas Instruments (TI) to cater to a wide range of applications requiring piezoelectric actuation or sensing. This IC is well-suited for industrial, medical, automotive, and consumer electronics markets, where precision driving of piezoelectric elements is crucial.

Key Features

• Integrated Boost Converter: The DRV2700RGPR includes an integrated boost converter that is capable of providing an output voltage up to 105V from a supply voltage as low as 3V. This feature allows the device to drive high-voltage piezoelectric loads without the need for an external high-voltage supply.
• High-Speed Amplifier: It comes with a high-speed amplifier that can drive both high-capacitive piezoelectric loads and non-piezoelectric high-voltage amplification needs.
• Flexible Input Signal: The input signal can be either analog or pulse-width modulated (PWM), giving designers the flexibility to choose the signal type that best fits their system requirements.
• Integrated Protection Features: The device includes over-current, thermal shutdown, and under-voltage lockout protections to ensure reliable operation under various conditions.

Applications

The DRV2700RGPR is designed for a multitude of applications that require precise control of piezoelectric elements, including but not limited to:

• Industrial sensors and actuators
• Medical imaging and diagnostic equipment
• Automotive fuel injectors and haptic feedback devices
• Consumer electronics such as precision micro-positioners
