Pin Functions
(*): The pin assignment of the TB6560AFG is different from that of the TB6560FG.
TB6560AHQ: There is no no-connect (NC) pin.
TB6560AFG: Except the above pins, all pins are NC. The pin numbers of NC pins are: 1, 3, 5, 8, 9, 12, 15, 17, 18,
Applying a voltage to NC pins does not cause any problem since they are not connected inside the IC.
All control input pins have an internal pull-down resistor of 100 kΩ (typ.)
Note 1: As for the TB6560AFG, two pins that have the same functionality should be short-circuited at a location as
