Overview
The DRV2665RGPT is a piezo haptic driver featuring an integrated digital frontend. It includes a 105-V boost switch, power diode, and fully-differential amplifier. The device supports I2C bus control up to 400 kHz. It operates within a supply voltage range of 3 V to 5.5 V. The output voltage reaches 200 V. The component is housed in a 20-pin QFN package measuring 4x4 mm. Operating temperatures span from -40°C to +85°C.
Feature Summary
- Integrates a high-voltage boost converter and differential amplifier for piezo actuation
- Features a digital frontend with I2C interface for direct control
- Provides full-bridge output configuration for haptic feedback
Applications
- Piezo haptic feedback systems
- Mobile device vibration modules
- Consumer electronics tactile interfaces
Procurement Notes
Verify the specific suffix RGPT against the official Texas Instruments datasheet to confirm pinout and thermal characteristics. Ensure the design accounts for the 20-QFN package dimensions and moisture sensitivity level. Confirm that the I2C address settings align with the system requirements before finalizing procurement.
Selection Notes
Select this component when a compact solution for piezo actuators is required. The integrated boost eliminates external inductor needs. Verify compatibility with the host microcontroller's I2C speed. Check that the 200 V output capability matches the piezo element specifications. Consider the QFN package for space-constrained PCB layouts.
Part Context
This part belongs to the DRV2665 series of piezo haptic drivers. It is designed to replace discrete solutions by integrating power stages and control logic. The device simplifies the design of haptic feedback loops in portable electronics. It serves as a specialized motor driver for capacitive loads rather than electromagnetic motors.
Replacement Considerations
The DRV2667RGPT is a related variant with similar packaging but different internal features. Verify functional equivalence regarding boost voltage and amplifier configuration before substitution.
