There are automotive applications for indicators and for LCD local-dimming backlighting. For these applications, more persons think multi-channel constant-current LED drivers are necessary. The requirement is to get the same intensity and color temperature of LEDs. For system-level safety, it is necessary that the LED drivers can sense faults.

The TLC6C5724-Q1 device is an automotive 24-channel constant-current RGB LED driver that can do tests on the LEDs. The TLC6C5724-Q1 device supplies a maximum of 50‑mA output current set by an external resistor. The device has a 7-bit dot correction with two ranges for each output. The device also has an 8-bit intensity control for the outputs of each color group. A 12-,10-, or 8-bit grayscale control adjusts the intensity of each output. The device has circuits that sense faults in the system, including LED faults, adjacent-pin short faults, reference-resistor faults, and more. A slew rate control has 2 positions for adjustment to get the largest decrease in system noise. There is an interval between the changes of output level from one LED group to a different one. This interval helps to decrease the starting electrical current. The SDI and SDO pins let more than one device be connected in series for control through one serial interface.
