产品描述

LP5560 is a programmable LED driver that can generate variety of blinking sequences with up to three pulses of different length per sequence. Blinking sequences can be programmed through single wire interface. Programmable parameters include on and off times as well as rise and fall times. Default sequence is programmed into LP5560 to enable the use of device in simple systems without programming capabilities.

Very low headroom voltage eliminates the need for boost converter. Indicator LEDs can be driven directly from the battery. Small package size combined with zero external components minimizes the solution size.

LP5560 is available in TI’s tiny 4-bump DSBGA package with 0.4 mm pitch.
