Setting the VTRIP Voltage
This procedure is used to set the VTRIP to a higher or
lower voltage value. It is necessary to reset the trip
point before setting the new value.
To set the new VTRIP voltage, start by setting the WEL
bit in the control register, then apply the desired VTRIP
threshold voltage to the VCC pin and the programming
voltage, VP, to the WP pin and 2 byte address and 1
byte of “00” data. The stop bit following a valid write
operation initiates the VTRIP programming sequence.
Bring WP LOW to complete the operation.
Resetting the VTRIP Voltage
This procedure is used to set the VTRIP to a “native”
voltage level. For example, if the current VTRIP is 4.4V
and the new VTRIP must be 4.0V, then the VTRIP must
be reset. When VTRIP is reset, the new VTRIP is some-
thing less than 1.7V. This procedure must be used to
set the voltage to a lower value.
To reset the new VTRIP voltage start by setting the
WEL bit in the control register, apply VCC and the pro-
gramming voltage, VP, to the WP pin and 2 byte
address and 1 byte of “00” data. The stop bit of a valid
write operation initiates the VTRIP programming
sequence. Bring WP LOW to complete the operation.
