TC62D722CFNG TOSHIBA CDMOS Integrated Circuit Silicone Monolithic TC62D722CFNG 16-Output constant current LED driver with the output gain control function and the PWM grayscale function Feature The TC62D722CFNG is LED drivers which have the sink-type constant current output. The 8-bit output gain control function and 16, 14, 12, and 10-bit PWM grayscale functions are built in this IC. Output current values of 16 channels can be set by one external resistance. In addition, the thermal shutdown function, the output open detection function, and the output short detection function are built in. This product is suitable for LED modules and lighting displays.
