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.

8-3-1) S2 command (Input of the output ON/OFF data.)
When this function is not used, this input is unnecessary.
Operation) In the number of SCK pulses at TRANS="H" is 7 or 8, the following operation is executed.
Input of the output ON/OFF data.
Even if PWM data is not changed to 0 settings, ON/OFF of the output can be controlled.
Note) About the output operation when this command is input while PWM output.
1. When the PWM counter is the synchronous mode. Note1
The setting of this command is reflected in the next PWM output.
2. When the PWM counter is the asynchronous mode. Note1
The setting of this command is reflected immediately.
The PWM counter synchronization function is set by S6 command.
Basic input pattern of S2 command)
Note1: PWM output synchronization PWM resolution is set by the S6 command.
Default setting is “Synchronous mode”.
