TLC59108F and TLC59108 - the main difference

Other Parts Discussed in Thread: TLC59108F, TLC59108

Hi all

Would you mind if we ask TLC59108F and TLC5910?

What is the difference between TLC59108F and TLC59108?
It seems that there is only LED Open Detection, but if you have some information, could you let us know it?

Kind regards,

I apologize Hirotaka,

The TLC59108 and TLC59108F are similar devices with the difference being the output structure. The TLC59108

has 8 constant-current outputs while the TLC59108F has 8 open drain outputs. The REXT is used to program

the current on the TLC59108 for all channels. The in-line resistors on the OUT pins are used in conjunction with

the VLED to set the currents on each TLC59108F channel. Since the resistors are unique for each output, the

currents can be set by output by changing the resistor value.

Overall, if the output LEDs all use the same current, the TLC59108 will work with a single resistor on the REXT pin.
