3 Description
The 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 a single-wire
interface. Programmable parameters include on and
off times as well as rise and fall times. Default
sequence is programmed into the LP5560 to enable
the use of device in simple systems without
programming capabilities.
Very low headroom voltage eliminates the need for a
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-pin DSBGA package
with 0.4-mm pitch.
