OV LATCH (ADM2914-1)
If an overvoltage condition occurs when the LATCH pin is
pulled low, the OV pin latches low. Pulling LATCH high clears
the latch. If an OV condition clears while LATCH is high, the
latch is bypassed and the OV pin behaves in the same way as the
UV pin, with an identical timeout period. If the LATCH pin is
pulled low while the timeout period is active, the OV pin
latches low, as in normal operation.

DISABLE (ADM2914-2)
Pulling the DIS pin high disables both the UV and OV outputs,
and forces both outputs to remain weakly pulled high, regard-
less of any faults that are detected at the inputs. If a UVLO
condition is detected, the UV output is asserted and pulls low;
however, the timeout function is bypassed. As soon as the
UVLO condition clears, the UV output pulls high. To guarantee
normal operation when the pin is left unconnected, DIS has a
weak 2 μA internal pull-down current.
