FAH4830 haptic driver with higher response time for touch screen design

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
