Fairchild Semiconductor’s Haptic Drivers Provide Solutions You Can Feel for a Richer, More User-Friendly Experience

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.

Key Features:

  • Easy to implement, turn-key solution reduces bill of material (BOM) costs
  • Low standby current (<500nA)
  • Fast wake-up time
  • Register based I2C control for design flexibility
  • Filter and gain control for reduced PWM noise

By offering power and analog solutions for one of the world's most dynamic markets for mobile technology and by combining inventive mobile solutions, Fairchild is able to provide the interaction and convenience features that deliver an exceptional user experience. Shipping over four billion units per year, Fairchild is a supplier of choice for every major mobile device and chipset provider, with components inside virtually every handset in the world.

Packaging and Pricing Information (in US 1,000 quantity pieces)

Samples available upon request - Delivery 8-12 weeks ARO

Available in a 10L MLP, 3X3 X 0.8mm package, FAH4830 haptic driver is priced at $1.10.

In most cases, it is convenient to have some human interaction with a web (micro-)service, no matter how small it is. A traditional approach would be to create an HTTP interface, where user requests will be dispatched and HTML/CSS pages must be served. This approach is indeed very traditional for a web site, but not really convenient for a web service, which is not intended to be good looking, 24x7 up and running and UX-optimized. Instead, talking to a web service in a chat-bot mode would be muc...
More and more companies are looking to microservices as an architectural pattern for breaking apart applications into more manageable pieces so that agile teams can deliver new features quicker and more effectively. What this pattern has done more than anything to date is spark organizational transformations, setting the foundation for future application development. In practice, however, there are a number of considerations to make that go beyond simply “build, ship, and run,” which changes ho...

Advances in technology and ubiquitous connectivity have made the utilization of a dispersed workforce more common. Whether that remote team is located across the street or country, management styles/ approaches will have to be adjusted to accommodate this new dynamic.

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

It's easy to assume that your app will run on a fast and reliable network. The reality for your app's users, though, is often a slow, unreliable network with spotty coverage. What happens when the network doesn't work, or when the device is in airplane mode? You get unhappy, frustrated users. An offline-first app is an app that works, without error, when there is no network connection.
The cloud promises new levels of agility and cost-savings for Big Data, data warehousing and analytics. But it’s challenging to understand all the options – from IaaS and PaaS to newer services like HaaS (Hadoop as a Service) and BDaaS (Big Data as a Service). In her session at @BigDataExpo at @ThingsExpo, Hannah Smalltree, a director at Cazena, will provide an educational overview of emerging “as-a-service” options for Big Data in the cloud. This is critical background for IT and data profes...

Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed.

Hurwitz, President and CEO of Hurwitz & ...
As someone who has been dedicated to automation and Application Release Automation (ARA) technology for almost six years now, one of the most common questions I get asked regards Platform-as-a-Service (PaaS). Specifically, people want to know whether release automation is still needed when a PaaS is in place, and why. Isn't that what a PaaS provides? A solution to the deployment and runtime challenges of an application? Why would anyone using a PaaS then need an automation engine with workflow ...

Your business relies on your applications and your employees to stay in business. Whether you develop apps or manage business critical apps that help fuel your business, what happens when users experience sluggish performance?
