The ON Semiconductor Eight Channel Enhanced 100 mA Linear Current Regulator and Controller for Automotive LED Lighting in Daisy Chain Sequencing Application Evaluation Board will demonstrate to the user this functionality using NCV7683 devices in a daisy chain fashion along with the typical DC current drive and PWM demonstration, the three typical control inputs into the system are available through on−board switches or through the pin connections to external controls, the three system control inputs are the STOP, TAIL, and TURN functions, the STOP function displays a 100% duty cycle current through the LEDs, the TAIL function displays a programmable PWM current through the LEDs, the TURN function displays the sequence event through the 8 on−chip channels and through a serial connection through a second series of 8 channels on a second device.
