Excellent recognition ability Fairchild Semiconductor develops FAH4830 haptic driver

Touch screen technology is the main technology of many electronic products today, but the haptic technology that drives the development of touch screens encounters the problems of slow response time and large battery consumption. Fairchild Semiconductor Corporation (NYSE: FCS) has developed the FAH4830 haptic driver to help designers meet these challenges and enhance the end-user experience with excellent recognition capabilities and a user-friendly interface.

When the user operates the touch screen, the FAH4830 haptic driver provides a sense of touch. Sensory interaction between users and mobile devices (such as tablets, personal computers, medical devices, video game systems, and smartphones) produces a more localized effect and ensures the user's correct "touch point" on the screen.

FAH4830 driver can directly drive eccentric rotating mass (ERM) motor and linear resonator (LRA), and make the contact point produce vibration. The typical driver wake-up time of the device is “30µS, which helps to reduce the delay time and provide fast tactile response.

The main function:

· Easy to implement, complete solution reduces the bill of materials (BOM) cost

· Low standby current (《500nA）

· Quick wake-up time

· Register-based I2C control for design flexibility

· Filter and gain control to reduce PWM noise

By providing power and analog solutions for mobile technologies in one of the world's most dynamic markets, combined with creative mobile solutions, Fairchild Semiconductor can provide interactive and convenient functions with a superior user experience. Fairchild delivers more than 4 billion units annually for almost all mobile phone internal components in the world and is the preferred supplier and chipset provider for all mainstream mobile devices.
