7.1 Overview

In automotive indicator and local dimming backlighting applications, the demand for multi-channel constant current LED drivers is increasing to achieve uniformity of LED brightness and color temperature. System-level safety considerations require fault detection capability and device self-check features.

The TLC6C5716-Q1 is an automotive 16-channel constant-current LED driver with LED diagnostics. The TLC6C5716-Q1 provides up to 50 mA of output current set by an external resistor. The current can be adjusted by 7-bit dot correction with two subranges for individual outputs, and an 8-bit brightness control for all the outputs of each color group. The brightness can be adjusted individually for each channel through a 12-, 10-, or 8-bit grayscale control. Fault-detection circuits are available to detect system faults including LED faults, adjacent-pin short faults, reference-resistor faults, and more. Negate bit toggle and LOD-LSD self-test provide a device self-check function to improve system reliability. Configurable slew-rate control optimizes the noise generation of the system and improves the system EMC performance. Output-channel group delay helps to reduce inrush current to optimize the system design. The SDI and SDO pins allow more than one device to be connected in a daisy chain for control through one serial interface.
