DRV2603RUNT

Overview

The DRV2603RUNT is a haptic driver from Texas Instruments designed for Linear Resonant Actuators (LRA) and Eccentric Rotating Mass (ERM) motors. It operates within a supply voltage range of 2.5 V to 5.2 V and features an operating current of 1.7 mA. The device supports frequencies between 10 kHz and 250 kHz, with a junction temperature range of -40°C to +150°C. It utilizes a 10-WQFN (2x2 mm) package in a Reel configuration.

Feature Summary

• Integrates full control and power stages for LRA and ERM actuation
• Features auto resonance tracking for optimized performance
• Supports parallel and PWM interface modes

Applications

• Haptic feedback systems
• Mobile device vibration modules
• Wearable technology actuators

Procurement Notes

Verify the specific suffix 'RUNT' against the official datasheet to confirm package dimensions and tape/reel specifications. Ensure compatibility with the target application's voltage requirements, which range from 2.5 V to 5.2 V. Confirm moisture sensitivity level (MSL 2) handling procedures during assembly to prevent damage.

Selection Notes

Select this component when designing compact haptic solutions requiring integrated power MOSFETs. It is suitable for applications needing support for both LRA and ERM types without external drivers. Consider the 10-WQFN footprint for space-constrained PCB layouts.

Part Context

This part belongs to the DRV2603 series, focusing on efficient haptic driving. It differs from other series like DRV2605 by lacking internal waveform memory, relying instead on external control signals. The RUNT variant specifies the reel packaging format for automated surface-mount assembly.
