Overview
The DRV2603RUNR is a haptic driver from Texas Instruments designed for ERM and LRA motors. It operates on a supply voltage range of 2.5 V to 5.2 V with a typical quiescent current of 1.7 mA. The device features an integrated power stage and supports PWM or parallel interfaces. It includes auto-resonance tracking functionality to maintain optimal vibration performance. The component is housed in a WQFN-10 package (2x2 mm) and functions within a temperature range of -40°C to +85°C, suitable for compact mobile applications.
Feature Summary
- Integrates full control logic and power MOSFET stages for direct motor driving
- Automatically tracks resonant frequency changes in Linear Resonant Actuators
- Supports standard PWM and parallel digital input interfaces
Applications
- Haptic feedback systems in smartphones and tablets
- Vibration actuators in wearable devices
- Motor control in portable consumer electronics
Procurement Notes
Verify the suffix 'RUNR' corresponds to the tape-and-reel packaging variant when ordering. Confirm the specific revision level matches your design requirements. Ensure compatibility with the 10-WQFN footprint during PCB layout. Cross-reference the datasheet for moisture sensitivity classification before assembly processing.
Selection Notes
Select this component for designs requiring low standby current and automatic resonance tuning. It is appropriate for space-constrained layouts due to its small WQFN package. Consider interface compatibility with the host microcontroller's available GPIO or PWM pins. Evaluate thermal dissipation needs based on the expected duty cycle and ambient conditions.
Part Context
This part belongs to the DRV2603 family of haptic drivers. It serves as a simplified alternative to more complex controllers by integrating the necessary power stage. The RUNR suffix indicates a reel-packaged version intended for automated surface-mount assembly processes.
Replacement Considerations
The DRV2603EVM-CT is an evaluation module, not a direct pin-to-pin replacement. Check for other DRV2603 variants with different suffixes if packaging differences are critical. Verify that any substitute maintains the same WQFN-10 outline and electrical specifications.
