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 correspond-
ing input pin (V
CC
, V2MON or V3MON). Then, a pro-
gramming 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
CR 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” accord-
ing to the procedure described below. Once V
TRIPx
has
been “reset”, then V
TRIPx
can be set to the desired volt-
age 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 volt-
age (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 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 CR regis-
ter before performing this write sequence.
After being reset, the value of V
TRIPx
becomes a nomi-
nal value of 1.7V.
V
TRIPx
Accuracy (x=1,2,3).
The accuracy with which the V
TRIPx
thresholds are set,
can be controlled using the iterative process shown in
Figure 24.
If the desired threshold is less that the present thresh-
old voltage, then it must first be “reset” (See "Resetting
the V
TRIPx
Voltage (x=1,2,3).").
The desired threshold voltage is then applied to the
appropriate input pin (V
CC
, V2MON or V3MON) and
the procedure described in Section “Setting a Higher
V
TRIPx
Voltage“ must be followed.
Once the desired V
TRIPx
threshold has been set, the
error between the desired and (new) actual set thresh-
old can be determined. This is achieved by applying
V
CC
to the device, and then applying a test voltage
higher than the desired threshold voltage, to the input
pin of the voltage monitor circuit whose V
TRIPx
was
programmed. For example, if V
TRIP2
was set to a
desired level of 3.0 V, then a test voltage of 3.4 V may
be applied to the voltage monitor input pin V2MON. In
the case of setting of V
TRIP1
then only V
CC
need be
applied. In all cases, care should be taken not to
exceed the maximum input voltage limits.
