There are various LED indicators in automotive applications. Some applications such as hybrid instrument clusters and E-shifters have safety requirements which must have LED fault diagnostics; other applications such as HVAC panels only have an LED on-off control, which does not require LED diagnostics. To cover both applications, the TLC6C5816-Q1 device implements a flexible LED diagnostics function. By writing to the registers, the output channels can be configured with LED diagnostics features or without LED diagnostics features.

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 channels with power DMOS transistor outputs. Eight of the channels support LED fault diagnostics by configuring corresponding registers, the device can drive 16 channels without diagnostics or 8 channels with diagnostics. The diagnostics channels DIAGn must connect to DRAINn to realize LED diagnostics. A command error fault implies that a channel is configured for LED diagnostics but a register write command has turned 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 to determine whether the communication loop between MCU and device is good.
