The X46402 is shipped with standard V
voltages. These values will not change over normal oper-
ating 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 volt-
age control signal.
AND V2MON THRESHOLD RESET PROCEDURE
TRIP
and V2
TRIP
Setting the V
This procedure is used to set the V
voltage value. For example, if the current V
and the new V
TRIP
is 4.6V, this procedure will directly
make the change. If the new setting is to be lower than
the current setting, then it is necessary to reset the trip
point before setting the new value.

Voltage
TRIP
,V2
TRIP
to a higher
is 4.4V
TRIP
To set the new voltages, apply the desired V
TRIP
thresh-
old voltage to the Vcc pin, the V2
TRIP
voltage to the
V2MON pin, then tie the RESET pin to the programming
voltage V
P
. Then, write data 01h or 0Dh address 00h to
program V
TRIP
, V2
TRIP
respectively. The stop bit following
a valid write operation initiates the programming
sequence. Bring RESET
LOW to complete the operation.
Note: this operation also writes 01h, or 0Dh to address
00h.
Resetting the V
TRIP
Voltage
This procedure is used to set the V
TRIP
, the V2
TRIP
to 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 procedure must be
used to set the voltage to a lower value.
To reset the new V
TRIP
, V2
TRIP
voltage, apply the desired
V
TRIP
or V2
TRIP
threshold voltage to the Vcc or V2MON
pin, respectively, and tie the RESET pin to the program-
ming voltage V
P
. Then write 03h or 0Fh to address 00h.
The stop bit of a valid write operation initiates the pro-
gramming sequence. Bring RESET
LOW to complete the
operation. Note: this operation also writes 03h or 0Fh to
address 00h of the EEPROM array.
