Under Voltage Lock Out
In order to avoid anomalous behaviors of the device when the supply voltage is too low to
support its internal rails, UVLO is provided: the device will start up when VCC reaches
UVLO upper threshold and will shutdown when VCC drops below UVLO lower threshold.
The 4.1V maximum UVLO upper threshold allows L6726A to be supplied from 5V and 12V
busses in or-ing diode configuration.
