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.

Introduction
1.3.2 Additional Items Required
• PC on which to install the TLC6C5816EVM GUI
• DC supply or USB port for LED supply
1.3.3 EVM Parameters
Table 1 shows the typical parameters of TLC6C5816EVM.
V
CC
LED supply 12 V typical
Channel current 20 mA at 12-V LED supply
NOTE: Channel current is set at 20 mA when the LED supply voltage is 12 V. Although the
TLC6C5816-Q1 device can withstand a 40-V maximum LED supply voltage, increased LED supply voltage increases channel output current. Make sure the channel current is within 50 mA when using higher LED supply voltage.
