Typical Application
The typical application for a haptic driver is in a touch-enabled system that already has an application processor which makes the decision on when to execute haptic effects.
The DRV2605 device can be used fully with I 2 C communications (either using RTP or the memory interface). A system designer can chose to use external triggers to play low-latency effects (such as from a physical button) or can decide to use the PWM interface. Figure 54 shows a typical haptic system implementation. The system designer should not use the internal regulator (REG) to power any external load.
A system designer can also implement audio-to-vibe. Figure 55 shows a typical haptic system implementation supporting audio-to-vibe.
