2. Always use the specified components for peripheral circuits so as to ensure that OV_EE and V_L do not reverse
potentials when the power is turned off.
As the above sketch illustrates, allowing OV_EE to exceed V_L1 and V_L2 by more than 0.7 V produces the risk
of applying a forward bias to the PN junction, turning on the parasitic transistor, and generating an
overcurrent that produces latch-up.
If this phenomenon arises, increase the size of capacitor C8 or decrease the size of capacitor C10 to increase
the OV_EE time constant.
(See the sample application circuit for the locations of C8 and C10.)
