9.2 Typical Application
A typical application of the DRV2624 device is in a system that has external buttons which fire different haptic
effects when pressed. Figure 97, Figure 98 and Figure 99 show typical schematics of such a system. The
buttons can be physical buttons, capacitive-touch buttons, or GPIO signals coming from the touch-screen
system.
Effects in this type of system are programmable.
