Setting the V
TRIP
Voltage
This procedure is used to set the V
TRIP
to a higher or
lower voltage value. It is necessary to reset the trip
point before setting the new value.
To set the new V
TRIP
voltage, start by setting the WEL
bit in the control register, then apply the desired V
TRIP
threshold voltage to the V
CC
pin and the programming
voltage, V
P
,
to the WP pin and 2-byte address and 1
byte of “00” data. The stop bit following a valid write
operation initiates the V
TRIP
programming sequence.
Bring WP
LOW to complete the operation.
Resetting the V
TRIP
Voltage
This procedure is used to set the V
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 V
TRIP
is reset, the new V
TRIP
is some-
thing less than 1.7V. This procedure must be used to
set the voltage to a lower value.
To reset the new V
TRIP
voltage start by setting the
WEL bit in the control register, apply the desired V
TRIP
threshold voltage to the V
CC
pin and the programming
voltage, V
P
, to the WP pin and 2-byte address and 1
byte of “00” data. The stop bit of a valid write operation
initiates the V
TRIP
programming sequence. Bring WP
LOW to complete the operation.
