3 Description

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 readback

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.
