Setting a V TRIPx Voltage (x = 1,2,3)
There are two procedures used to set the threshold voltages

higher or lower than the present value. For example, if the
present V TRIPx is 2.9 V and the new V TRIPx is 3.2 V, the
new voltage can be stored directly into the V TRIPx cell. If
however, the new setting is to be lower than the present

setting, then it is necessary to “reset” the V TRIPx voltage
before setting the new value.

FIGURE 21. VOLTAGE MONITOR RESPONSE
V2 Monitoring
The X9520 asserts the V2RO output HIGH if the voltage V2
exceeds the corresponding V TRIP2 threshold (See Figure
21). The bit V2OS in the CONSTAT register is then set to a
“0” (assuming that it has been set to “1” after system
initilization).
The V2RO output may remain active HIGH with V CC down to
1V.
V3 Monitoring
The X9520 asserts the V3RO output HIGH if the voltage V3
exceeds the corresponding V TRIP3 threshold (See Figure
21). The bit V3OS in the CONSTAT register is then set to a
“0” (assuming that it has been set to “1” after system
initilization).
The V3RO output may remain active HIGH with V CC down to
1V.
V TRIPx Thresholds (x = 1,2,3)
The X9520 is shipped with pre-programmed threshold
(V TRIPx ) voltages. In applications where the required
thresholds are different from the default values, or if a higher

Setting a Higher V TRIPx Voltage (x = 1,2,3)
To set a V TRIPx threshold to a new voltage which is higher
than the present threshold, the user must apply the desired
V TRIPx threshold voltage to the corresponding input pin
(V1/VCC, V2 or V3). Then, a programming voltage (Vp) must
be applied to the WP pin before a START condition is set up on
SDA. Next, issue on the SDA pin the Slave Address A0h,
followed by the Byte Address 01h for V TRIP1 , 09h for
V TRIP2 , and 0Dh for V TRIP3 , and a 00h Data Byte in order to
program V TRIPx . The STOP bit following a valid write
operation initiates the programming sequence. Pin WP must
then be brought LOW to complete the operation (See Figure
23). The user does not have to set the WEL bit in the
CONSTAT register before performing this write sequence.
Setting a Lower V TRIPx Voltage (x = 1,2,3).
In order to set V TRIPx to a lower voltage than the present
value, then V TRIPx must first be “reset” according to the
procedure described below. Once V TRIPx has been “reset”,
then V TRIPx can be set to the desired voltage using the
procedure described in “Setting a Higher V TRIPx Voltage”.
Resetting the V TRIPx Voltage (x = 1,2,3).
To reset a V TRIPx voltage, apply the programming voltage
(Vp) to the WP pin before a START condition is set up on SDA.
Next, issue on the SDA pin the Slave Address A0h followed
by the Byte Address 03h for V TRIP1 , 0Bh for V TRIP2 , and
0Fh for V TRIP3 , followed by 00h for the Data Byte in order to
reset V TRIPx . The STOP bit following a valid write operation
