SLOS740C May 2012 – January 2023 DRV2665
PRODUCTION DATA
The typical application for a haptic driver is in a touch-enabled system that already has an application processor that makes the decision on when to execute haptic effects.
The DRV2665 device is configured and can be used fully with I2C communication to stream or launch haptic effects. Additionally, the system designer may decide to use the analog input to stream the desired haptic effects.
