Fairchild Semiconductor has developed the FAH4830 haptic driver with higher response time for touch screen design. The FAH4830 haptic driver provides a touch sensation when a user interacts with a touch screen. The sensory interaction between the user and mobile device – such as tablets, PCs, medical devices, video games systems and smart phones – creates a more local effect and assures the user of a correct "point-of-touch" on the screen.
Offering direct driving capability of eccentric rotating mass (ERM) motors and linear resonant actuators (LRA), the FAH4830 driver enables a vibrating sensation on point-of-contact. The typical driver wake-up time of the device is
