2.1.4 EN

EN is a 3-pin header used to enable or disable the TPS7A14.

The center pin of the 3-pin header is tied to the TPS7A14 EN input. When the 2-pin shunt is placed across the top two pins of the header, VIN is shorted to EN, and the TPS7A14 is enabled. When the 2-pin shunt is placed across the bottom two pins of the header, GND is shorted to EN, and the TPS7A14 is disabled.

When driving the EN terminal with an off-board supply or signal generator, the applied voltage must be kept between 0 V and 5.5 V.
