TC62D723FNG TOSHIBA CDMOS Integrated Circuit Silicone Monolithic TC62D723FG 16-Output constant current LED driver with the output gain control function and the PWM grayscale function 1.Feature The TC62D723FNG is LED drivers which have the sink-type TC62D723FNG constant current output. The output gain control function of 8-bit and the PWM grayscale function of 16, 14, 12, and 10-bit are built into this IC. Output current value of 16 channels is set by one external resistance. In addition, the thermal shutdown function, the output open HTSSOP24-P-300-0.65 detection function, and the output short detection function are built in. This IC is most suitable for lighting the LED module and the display.
