Analog Devices, Inc. (ADI) has introduced the ADP8866 LED charge pump backlight driver with independent control of nine LED current sinks, programmable LED blinking sequences and low operating current drain.

Independent LED control allows the convenient control of backlighting LEDs and status indicator LEDs with one part.

Programmable fade on/off and blinking sequences allow complex LED effects to be generated automatically, saving processor bandwidth and power. A built-in charge pump automatically adjusts its gain to efficiently power the LEDs under all conditions.

Requiring less than 1 µA during standby and less than 325 µA during automated blinking sequences, the ADP8866 programmable LED driver’s low power consumption and simplified software interface make it an excellent choice for portable systems.
