Applications with the TPS2412/13 are not limited to ORing of identical sections. The TPS2412/13 and external
MOSFET form a general purpose function block. Figure 15 shows a circuit with ORing between a discrete diode
and a TPS2412/MOSFET section. This circuit can be used to combine two different voltages in cases where the
output is regulated, and the additional voltage drop in the Input 1 path is not a concern. An example is ORing of
an ac adapter on Input 1 with a lower voltage on Input 2.
Figure 15. ORing Circuit
The TPS2412 may be a better choice in applications where inputs may be removed, causing an open-circuit
input. If the MOSFET was ON when the input is removed, VAC will be virtually zero. If the reverse turn-off
threshold is programmed negative, the TPS2412/13 will not pull GATE low. A system interruption could then be
created if a short is applied to the floating input. For example, if an ac adapter is first connected to the unit, and
then connected to the ac mains, the adapter's output capacitors will look like a momentary short to the unit. A
TPS2412 with RSET open will turn the MOSFET OFF when the input goes open circuit.
