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.
