Haptic Drivers Deliver Unmatched Performance and 123 Royalty-Free Haptic Effects
DRV2604/5
DRV2604/5 functional block diagram
Haptics has been popular in gaming and mobile phones and TI’s DRV2604/5 ERM/
LRA haptic drivers make it easy to integrate haptics into any touch-enabled consumer
or industrial application. Enhancing the user experience presents a number of design
challenges, including software programming, system diagnostics, motor calibration and
haptic effect generation. The DRV2604/5 are truly differentiated solutions that address
these challenges and simplify system design.
Key Features
• DRV2605istheindustry’sfirstERM/
LRA haptic driver with 123 pre-load-
ed, royalty-free distinct haptic effects
designed and licensed by Immersion
•
Audio-to-hapticsmodeinDRV2605
automatically converts audio from
music, movies or games into haptic
effects allowing users to feel and fully
experience audio and video content
• SmartLooparchitecture
Automatic overdriving and braking simpli-
fies software programming and reduces
startup and braking time by 50%
