NOTE:
7. Between t1 and t2 the IN+ and IN- inputs must cause the OUT pin
LDEL
to go through one complete cycle (transition order is not impor-
tant). If the ENABLE pin is low after the undervoltage circuit is
satisfied, the ENABLE pin will initiate the 10ms time delay during
which the IN+ and IN- pins must cycle at least once.
