DRV2605LYZFT

Overview

The DRV2605LYZFT is a haptic driver from Texas Instruments designed for LRA and ERM actuators. It operates within a supply voltage range of 2 V to 5.2 V and draws a typical operating current of 500 uA. The device supports actuator frequencies between 125 Hz and 300 Hz, delivering an output voltage of 1.8 V. It features a single output configuration and utilizes an I2C interface. The component is housed in a DSBGA-9 package with surface mount installation. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports both Linear Resonant Actuators (LRA) and Eccentric Rotating Mass (ERM) motors
• Integrates control logic and power stage for simplified system design
• Enables flexible input control via I2C, PWM, or analog interfaces

Applications

• Haptic feedback systems in mobile devices
• Smartphone vibration motor control
• Wearable technology tactile interfaces

Procurement Notes

Verify the specific suffix ZFT corresponds to the DSBGA-9 tape and reel packaging format when ordering. Confirm that the low-voltage variant specifications align with your system's 2V to 5.2V power rail requirements. Ensure compatibility with the required I2C address settings and check for any recent product change notifications regarding the manufacturing site or material composition before finalizing procurement.

Selection Notes

Select this part for applications requiring low standby current and support for both LRA and ERM types. The DSBGA-9 package offers a compact footprint suitable for space-constrained designs. Consider the 1.8V output level against the actuator drive requirements. Compare against the standard DRV2605YZFT if higher voltage headroom or different thermal characteristics are needed for the specific application environment.

Part Context

This component belongs to the DRV2605L series, which focuses on low-voltage operation compared to the standard DRV2605 family. It shares functional similarities with the DRV2605LYZFR but differs in packaging format. The device integrates waveform generation capabilities, reducing the processing load on the host microcontroller by handling haptic effect playback internally through its embedded library.

Replacement Considerations

The DRV2605LYZFR serves as a direct replacement with identical electrical characteristics but in a reel packaging format instead of cut tape.
