产品概述
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.
