PRODUCTION DATA.
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, but 8 of the channels can instead be configured by the corresponding DIAGn bits in the Configuration register to support LED fault 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. This checks whether the communication loop between MCU and device is good.
