1 Introduction
The TLC6C5816-Q1 device is a 16-bit shift register LED driver designed to support automotive LED
applications. A built-in LED-open and LED-short diagnostic mechanism provides enhanced safety
protection. The device contains 16-channel power DMOS transistor outputs. Eight channels support LED
fault diagnostics by configuring corresponding registers. The diagnostics channels DIAGn must connect to
DRAINn to use the LED diagnostics. A command error fault implies that when a channel is configured for
LED diagnostics, a register write command turns on the channel at the same time. The device provides a
cyclic redundancy check to verify register values in the shift registers. In read-back mode, the device
provides 6 bits of the CRC remainder. The MCU can read back the CRC remainder and check if the
remainder is correct. This can check whether the communication loop between MCU and device is good.
