TC62D723FTAG
16-Output constant current LED driver with the output gain control function and the PWM grayscale function
1.General
The TC62D723FTAG 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.

H setting (Setting of Initialization function
H[0] Setting
0
The initialization function becomes not active.(Default)
It's normal operation mode.
The initialization function becomes active.
1 All data in IC is initialized.
After data initialization, it becomes normal operation mode.
L setting (Setting of standby mode (1) function)
L[0] Setting
0
The standby mode (1) function becomes not active. (Default)
It's normal operation mode.
The standby mode (1) function becomes active.
The circuits other than the logic circuit are turned off. And power supply current is reduced.
1 (All the data of the IC are stored. Data input is possible.)
When S0 command is inputted at the standby mode, IC returns to normal operation mode.
Return time to the normal operation mode is about 30 μs.
