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.

Selection of teh one-shot output PWM mode or the repeat PWM output mode is possible.

• Thermal shutdown function (TSD) built-in.

• Output error detection function built-in.

This function has the automatic operation and the command

input manual operation.

Output open detection function (OOD) and output short

detection function (OSD) built-in.

• Power-on-reset function built-in. (When the power supply is turned on, internal data is reset)

• Stand-by function built-in. (IDD=1μA at standby mode)

• Output delay function built-in. (Output switching noise is reduced)
