The DRV2605 is the only eccentric rotating mass actuator (ERM) and linear resonant actuator (LRA) haptic driver pre-loaded with a library of 123 distinct haptic effects designed and licensed by Immersion, the leading developer and licensor of touch feedback technology. The DRV2605 also features a smart loop architecture that reduces startup and braking time by half, delivers twice the vibration strength, and consumes 50-percent less power to extend battery life, compared to competitive solutions.  

The DRV2605’s pre-loaded Immersion haptic effects library offers a range of distinct and differentiated tactile effects for touch screen feedback, giving users a more satisfying and realistic experience.

The device automatically converts audio from music, movies or games into haptic effects. The audio mode adds a vibrating bass enhancement that allows users to feel and fully experience audio and video content.

The DRV2605’s smart loop architecture offers automatic overdriving and braking for ERMs and LRAs, which simplifies software programming and reduces startup and braking time by 50 percent. Automatic resonance tracking for the LRA delivers twice the vibration force at half the power of competitive solutions. In addition, the automatic actuator diagnostics and level tracking feature delivers consistent acceleration over a range of environmental conditions.

At 1.5-mm by 1.5-mm, the DRV2605 claims to offer designers the industry’s smallest package for space-constrained portable applications.

The DRV2605 combines with any member of TI’s touch screen controller family to create a complete touch screen solution.

The DRV2605 joins the DRV2604 ERM/LRA haptic driver, which shares the same core and industry-leading performance and power-saving features, minus the audio-to-haptics mode and Immersion haptic effects library.

Availability and Pricing

The DRV2605 is available in a 9-ball, 1.5-mm by 1.5-mm by 0.6-mm WCSP package for a suggested retail price of $1.60 in 1,000-unit quantities. The DRV2604 is also available for a suggested retail price of $1.15 in 1,000-unit quantities.

Evaluation modules (EVMs) are available for the DRV2605 and DRV2604, each for a suggested retail price of $99. The EVMs are supplied with user guides and include a fully programmable MSP430G2553 Value Line microcontroller, sample haptic effects and capacitive touch buttons, as well as analog, I2C and PWM digital interfaces for complete standalone and in-system evaluation. The DRV2605 includes an API software driver for the Immersion haptic effects library.
