8.2 Typical Application

Following is a typical automotive cluster application which contains 24 LEDs. Two TLC6C5816-Q1 devices connected in series drive the total of 24 LEDs. The first device drives 8 safety-critical LEDs which require LED diagnostics, and the second device drives 16 general-purpose LEDs which only require simple on-and-off control. An MCU, which controls the two devices through a serial interface and GPIOs, controls channel on-off, PWM dimming, and LED diagnostics functions.
