TPS62125 has an enable comparator with a rising threshold of 1.2V and falling threshold
of 1.15V. The EN_hys pin is pulled low when the SMPS is disabled, therefore allowing
for additional hysteresis to be added with an external resistor.

The values chosen give a rising supply threshold of 11.1V and a falling threshold of 9.6V.
This should ensure that the board does not turn on if an almost flat battery is connected
and that once the UVLO has tripped, it will not oscillate as the battery voltage recovers
slightly.

The capacitor connected to the EN pin forms a low-pass filter with the resistors, having
a time constant of 56ms. This is to prevent false triggering of the UVLO when outputs
connected to large capacitances are turned on. This allows for up to 400mF on an output.
