Fairchild Offers LED Driver In Small Form Factor For Blinking LED Applications
Fairchild Semiconductor announced its FAN5645, a single wire programmable LED driver, which is claimed to offer a flexible and compact solution for blinking LED indicators. This device records a blinking pattern and plays it indefinitely, eliminating the need for continual system processor control. This is said to result in significant energy savings and longer battery life since the FAN5645 consumes much less current (33µA Typ.) when compared to a system processor’s consumption in the mA range.
The autonomous operation of the FAN5645 LED driver is said to eliminate the need for an interrupt driven processor to control the sequencing of the LED, freeing up processor bandwidth. Packaged in a compact MLP 3.0 x 3.0mm package, the FAN5645 is suitable for space-constrained portable and battery-operated applications such as cell phones, toys, home appliances, mobile computing, Bluetooth peripherals, rechargeable flashlights, motion sensors and power tools.
The FAN5645 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. The device is designed to meet the requirements of the European Union’s Directive on the restriction of the use of certain substances (RoHS).
The FAN5645 is priced (each, 1000 pcs) at $0.65, with a delivery time of 8-10 weeks ARO.
