voltages. These values will not change over
normal operating and storage conditions. However, in
applications where the standard thresholds are not
exactly right, or if higher precision is needed in the
threshold value, the X46402 trip points may be
adjusted. The procedure is described below, and uses
the application of a high voltage control signal.

Resetting the V
This procedure is used to set the V
a “native” voltage level. For example, if the current
V
TRIP
is 4.4V and the new V
TRIP
must be 4.0V, then
the V
TRIP
must be reset. When the threshold is reset,
the new level is something less than 1.7V. This proce-
dure must be used to set the voltage to a lower value.
