Multi channel led driver features serial interface for easy programming

A new multi led driver with the ability to drive up to eight leds independently using any illumination process has been unveiled by ON Semiconductor.
The NCP1840 is targeted at led status indicators that communicate status and diagnostic conditions to the user. It is designed to help differentiate an end product via led animation and is aimed at portable applications due to its ability to extend battery life.
ON claims that by using the device, engineers can offload some of the work normally handled by the processor in their system design, as it no longer needs to directly control each individual led.
"The NCP1840 sets itself apart from other high end led drivers, thanks to the variety of innovative features it incorporates," said Ryan Cameron, vp of Custom Industrial and Timing Products at ON Semiconductor. "This device helps oems cost effectively use dynamic led illumination to communicate product status, diagnostic feedback, and to differentiate their products in increasingly competitive environments."
Designed for applications in the industrial, computing and consumer end markets, the new led driver is offered in a Pb free, RoHS compliant 4 x 4mm QFN-20 package and supports an operating temperature range of -40 to 85°C.
