Overview
The DRV2605LDGST is a low-voltage haptic driver from Texas Instruments designed for Linear Resonance Actuators (LRA) and Eccentric Rotating Mass (ERM) motors. It operates within a supply voltage range of 2 V to 5.2 V and features an I2C-compatible digital interface. The device integrates a waveform sequencer, trigger logic, and real-time playback mode. It utilizes a Smart-loop architecture for automatic overdrive, braking, and resonance tracking in LRA applications. The component is housed in a 10-VSSOP package with a maximum junction temperature rating of 150°C.
Feature Summary
- Integrated closed-loop control system with Smart-loop architecture for automatic resonance tracking and actuator diagnostics
- Built-in licensed Immersion TouchSense library providing pre-defined haptic effects and audio-to-vibe functionality
- Dual-mode drive capability supporting both open-loop and closed-loop operation via I2C or PWM input signals
Applications
- Mobile phones and tablets
- Watches and wearable technology
- Touch-enabled devices and industrial human-machine interfaces
Procurement Notes
Verify the specific suffix 'GSR' versus 'GST' when ordering, as these denote different tape-and-reel packaging configurations rather than functional differences. Confirm the 10-VSSOP package dimensions against your PCB footprint requirements. Ensure the design supports the required I2C bus speed and voltage levels compatible with the host processor. Check humidity sensitivity handling procedures during assembly.
Selection Notes
Select this component for applications requiring high-fidelity haptic feedback without complex external waveform generation circuitry. It is suitable for battery-powered devices due to its wide voltage operation and efficient differential switching output. Consider the integrated library if reducing development time for haptic effects is a priority. Verify compatibility with the target actuator type, specifically noting the automatic resonance tracking benefits for LRAs.
Part Context
This part belongs to the DRV2605L series of haptic drivers, which are designed to simplify the implementation of tactile feedback in consumer electronics. The series includes variants with different packaging options, such as the DGSR reel version. These drivers consolidate motor control, power driving, and waveform sequencing into a single IC, reducing board space and component count compared to discrete solutions.
Replacement Considerations
The DRV2605LDGSR is a functionally equivalent alternative differing primarily in packaging format (reel vs. cut tape). Other members of the DRV2605L family may offer similar performance but require verification of pinout and package compatibility.
