Fairchild Semiconductor’s Programmable LED Blinker Device Addresses the Design Challenge of Driving a Single-LED

SAN JOSE, Calif. — (BUSINESS WIRE) — September 1, 2009 Fairchild Semiconductor (NYSE: FCS) enables designers of mobile handsets, ultra-portable devices, consumer products and industrial/embedded systems to implement a blinking LED solution that can easily be programmed to create an enhanced visual experience. Fairchild’s programmable LED blinker, the FAN5646, eliminates the need for a microprocessor to be in continuous operation mode. With proprietary TinyWire™ single-wire digital interface, the FAN5646 can be programmed with a unique LED blink rate and pattern. When the FAN5646 is enabled it will continually play these LED blink patterns until commanded by the microprocessor to stop. Common approaches for solving this challenge include connecting the LED to an LDO regulator or a FET plus a lithium ion battery. Both of these implementations require a microprocessor to be programmed with a blinking pattern, draining battery life since the microprocessor needs to be continually operating to maintain this pattern.

The FAN5646 lowers the overall solution cost while providing the features and benefits designers are requesting. Key features include:

The FAN5646 is an example of Fairchild’s expertise in delivering novel lighting solutions that meet the design needs of the ultra-portable, consumer and industrial/embedded markets. Consumers today are demanding products to be visually appealing and with the FAN5646, Fairchild offers a solution to help meet these requirements while satisfying designers’ demands.
