San Jose, Calif. Fairchild Semiconductor has introduced the FAN5645, a single-wire programmable LED driver for blinking LED indicators. Housed in a compact MLP 3.0 x 3.0-mm 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 device records a blinking pattern and plays it indefinitely, eliminating the need for continual system processor control. This results in significant energy savings and longer battery life since the FAN5645 consumes much less current, typically 33 uA when compared to a system processor's consumption in the milliamp range, said Fairchild. The autonomous operation of the FAN5645 LED driver eliminates the need for an interrupt driven processor to control the sequencing of the LED, freeing up processor bandwidth.
The FAN5645 uses 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. All of Fairchild's products are RoHS compliant.
Pricing: $0.65 each in quantities of 1,000.
Availability: Samples are available now with delivery of eight to ten weeks ARO.
