Did somebody use the IQS127D, Single Channel Capacitive Proximity/Touch Controller?
I need some advise, i would like to be sure that i will calculate the right value Rb value for the BC327 of my switching circuit. I am little confused with the Datasheet, IQS127D sink current for Tout is 1mA and for Pout 3mA, is that correct?

Yes, it is odd the P and T outputs have different max ratings.

More important: what LOAD is the BC327 expected to drive? You need more than enough base current to saturate the BC327 into the load it drives. I don't have BC327 specs memorized, and I have no idea what your load is.
