The TLC592x-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 a single 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 multi-color
LEDs. An additional advantage of the independent outputs is the ability to leave unused channels
floating. The flexibility of the TLC592x-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.
