TC62D723FNAG
TOSHIBA CDMOS Integrated Circuit Silicone Monolithic
TC62D723FＮAG
16-Output constant current LED driver with the output gain control function and the PWM grayscale function
1.Feature
The TC62D723FNAG is LED drivers which have the sink-type
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
detection function, and the output short detection function are built
in.
This IC is most suitable for lighting the LED module and the display.
