Touch screen technology is a staple in many of today’s electronics, but the haptic technology that drives touch screens suffers slow response times and large battery drains. Fairchild Semiconductor (NYSE: FCS) developed the FAH4830 haptic driver to help designers overcome these challenges and enhance the end-user experience through excellent recognition and a user-friendly interface.

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 <30µS which helps to reduce latency and provides a fast haptic response.
