The currently selected source is indicated by the '''STAT''' pin; this pin is an open-drain output that is low if the external power source is selected and high-impedance if the USB supply is selected. The current limit of the TPS2113A is set to about 1.9 A nominally. For more information about the power multiplexer, see the [https://www.pololu.com/file/0J771/tps2113a.pdf fiche technique du TPS2113A] (1Mio pdf). | The currently selected source is indicated by the '''STAT''' pin; this pin is an open-drain output that is low if the external power source is selected and high-impedance if the USB supply is selected.
