Overview
The DRV2667RGPR is a piezo haptic driver manufactured by Texas Instruments, designed for high-fidelity tactile feedback. It integrates a boost converter, digital front end, and internal waveform memory within a QFN-20 package. The device operates on a supply voltage ranging from 3 V to 5.5 V with a typical operating current of 5 mA. It supports an output voltage up to 200 V and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a boost converter and digital front end for precise piezo actuator control
- Includes internal waveform memory for storing custom haptic patterns
- Supports I2C interface for digital configuration and control
Applications
- High-fidelity tactile feedback systems in mobile devices
- Industrial human-machine interfaces requiring precision vibration
- Medical handheld terminals needing reliable haptic response
Procurement Notes
Verify the suffix RGPR indicates tape and reel packaging when ordering. Confirm the component meets RoHS standards for environmental compliance. Ensure the supplier provides valid traceability documentation. Check that the part matches the specific QFN-20 package requirements. Validate compatibility with the intended system voltage levels before procurement.
Selection Notes
Select this component for applications requiring wide frequency response and high peak voltage. It is suitable where space constraints favor a compact QFN-20 footprint. Choose it over ERM drivers when zero static current and mechanical durability are priorities. Consider its digital control capabilities for complex waveform generation needs.
Part Context
This part belongs to the DRV2667 series of piezo haptic drivers. It differs from ERM/LRA drivers like the DRV2605 by focusing on direct piezo actuation. The series emphasizes integrated power management and digital signal processing for advanced tactile experiences.
Replacement Considerations
The DRV2665 is a related variant within the same family but may have different thermal specifications or feature sets. Verify pinout and electrical parameters before substitution. Consult official datasheets to confirm functional equivalence for specific design requirements.
