TLC6C5716QDAPRQ1 automobile 16 channel complete diagnosis constant current RGB LED driver price concessions
explain
The automotive industry needs LED and LCD local dimming backlight applications. For this type of application, most people believe that multi-channel constant current LED drivers are necessary. The requirement is to obtain the same LED brightness and color temperature. For system level security, LED drivers must be able to detect faults.
TLC6C5716-Q1 device is a 16 channel constant current RGB LED driver for vehicles, which can be tested in LED. The TLC6C5716-Q1 device can provide an output current of up to 50mA (set by an external resistor). The device has a 7-point correction, and each channel outputs 2 ranges. The device also has an 8-bit brightness control output for each color group.
The brightness of each output can be adjusted through 12 bit, 10 bit or 8 bit gray scale control. The circuit of the device can detect various system faults, including LED fault, adjacent pin short circuit fault, reference resistor fault, etc. The wobble rate control has 2 adjustable positions for maximum reduction
System noise. When the output level flows from one LED group to another, there is a certain time interval for its change. This time interval helps to reduce the starting current. SDI and SDO pins allow multiple devices to be connected in series and controlled through a serial interface.
