DRV2604LYZFT

Overview

The DRV2604LYZFT is a low-voltage ERM/LRA haptic driver from the Texas Instruments DRV2604L series. It operates within a supply voltage range of 2V to 5.2V and features a typical operating supply current of 500 uA. The device supports an I2C interface with a maximum clock frequency of 250 kHz. It is housed in a DSBGA-9 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrated waveform memory for storing and playing back haptic effects without external microcontroller intervention
• Supports both Eccentric Rotating Mass (ERM) and Linear Resonant Actuator (LRA) motor types
• Includes internal real-time feedback loop for automatic LRA resonance tracking

Applications

• Smartphone and tablet haptic feedback systems
• Wearable device vibration alerts
• Automotive control knob tactile feedback

Procurement Notes

Verify the specific suffix 'YZFT' against the official datasheet to confirm it denotes the tape-and-reel packaging variant of the DRV2604L. Ensure compatibility with the required DSBGA-9 footprint and reflow soldering profile. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for ERM or LRA motors is required. The low quiescent current makes it suitable for battery-powered portable devices. The integrated library simplifies design by reducing the processing load on the host processor compared to drivers requiring external waveform generation.

Part Context

This part belongs to the DRV2604L family, which focuses on low-power haptic driving. It differs from the standard DRV2604 by offering optimized performance for lower voltage applications while maintaining similar functional capabilities for generating precise haptic sensations in consumer electronics.

Replacement Considerations

The DRV2604LYZFR is a compatible reel variant. The DRV2604LDGST is a pin-compatible alternative in an MSOP-10 package.
