8 Application and Implementation
TLC6C5712-Q1
SLVSCO9A – AUGUST 2015 – REVISED AUGUST 2015
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLC6C5712-Q1 device is capable of driving different numbers of LEDs with accurate current driving and the
most-advanced diagnostics. The device is suitable for automotive cluster tell-tale lighting, gear-shifter PRNDL
indicators, and other safety-critical LED applications.
8.2 Typical Applications
8.2.1 Multiple Devices Connected in Cascade
The TLC6C5712-Q1 design supports multiple devices in cascaded daisy-chain mode. Each communication
sequence must only have one LATCH rising edge and, therefore, cannot be split into multiple smaller sequences.
