EN is a 3-pin header used to enable or disable the TPS7A53A-Q1.
The center pin of the 3-pin header is tied to the TPS7A53A-Q1 EN input. When the 2-pin shunt is placed across the two rightmost pins of the header, VIN is shorted to EN and the TPS7A53A-Q1 is enabled. When the 2-pin shunt is placed across the two leftmost pins of the header, GND is shorted to EN and the TPS7A53A-Q1 is disabled.
When driving the EN terminal with an offboard supply or signal generator, the applied voltage must be kept between 0 V and VIN.
