3 Description
The TLC591x-Q1 Constant-Current LED Sink Drivers
is designed to work alone or cascaded. Because
each output is independently controlled, they can be
programmed to be on or off by the user. The high
LED voltage (VLED) allows for the use of one LED
per output or multiple LEDs on a single string. With
independently controlled outputs supplied with
constant current, the LEDs can be combined in
parallel to create higher currents on a single string.
The constant sink current for all channels is set
through a single external resistor. This allows
different LED drivers in the same application to sink
various currents which provides optional
implementation of multicolor LEDs. An additional
advantage of the independent outputs is the ability to
leave unused channels floating. The flexibility of the
TLC591x-Q1 LED driver is ideal for applications such
as (but not limited to): automotive LED lighting, 7-
segment displays, scrolling single-color displays,
gaming machines, white goods, video billboards, and
video panels.
