Part Number: TLC59401 I'm trying to do a software code to use two TLC59401 in series. None of them work despite I do not see anything wrong with the code (all signals seem Ok in the logic analyzer). I have noticed a strange behavior in SOUT (see image…
Part Number: TLC59401 The pins 12, 13, 28 and 29 of TLC59401 are marked NC (no connection). Are they internally NC and could be connected to the PCB (any voltage) to make routing easier? Or must they be left not connected external on the PCB?
Part Number: TLC59401 Hi Team,
Our customer would like use Grayscale PWM function so they set GS Register value.
After that, they control ON/OFF of LED by the BLANK pin.
We understand that if BLANK pin is high, GS counter is reset but GS Register isn…
Part Number: TLC59401 Dears,
I hanve tested TLC59401 in my design. I met some problem when OUTX set from H to L ,and OUTX is L , VLED is also dropped low, I think there is some incorrect in my sch,So pls check it for me,
Thanks a lot.
Part Number: TLC59401 Hi Team,
Regarding the TLC59401, is it possible to make the maximum current software-adjustable, rather than forcing the user to swap resistors on the Iref pin? Could I accomplish this by driving Iref with a DAC directly instead of…
Part Number: DAC63204 Hi Team,
This post is related to our customer's application of DAC63204 with TLC59401RHBR which I post in the link below.

Other Parts Discussed in Thread: TLC59401 Hello,
I just need to be clear with information about additional SCLK after XLAT pulse of first GS mode data shift. This says datasheet for TLC59401 on page 18. But when you look at figure 12 on page 12 and figure…
Hello Iko,
Do you expect negative current going through the LEDs? I think the current will charge the capacitors connected on the LED power line, generating a higher voltage on that line.
So even if there is negative current on the LED power line, I…
