Requires 5 ceramic capacitors and one resistor to form complete LED power supply, current controller
Silicon offerings provider ON Semiconductor has introduced NCP1840, a multi-LED driver which drives up to eight LEDs independently, using any illumination pattern the user creates.
The NCP1840 differentiates an end product via LED animation and engineers can offload some of the work by utilising the NCP1840.
With NCP1840, current and dimming level programming is done by writing to and reading registers via a serial interface that uniformly controls the brightness and blink rate of each LED.
Due to its ability to extend battery life by using a high efficiency, low noise, quad-mode charge pump, the multi-LED driver is suited for portable applications.
NCP1840 also saves on space as it requires only five small ceramic capacitors and one resistor to form a complete LED power supply and current controller.
ON Semiconductor Custom Industrial and Timing Products vice-president Ryan Cameron said the NCP1840 sets itself apart from other high end LED drivers, thanks to the variety of innovative features it incorporates, so that engineering teams are not faced with having to compromise on design concepts.
"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," said Ryan Cameron.
