To set the new VTRIP voltage, apply the desired VTRIP
threshold voltage to the VCC pin and tie the WP pin to
the programming voltage VP. Then write data 00hto
address 01h. The stop bit following a valid write operation
initiates the VTRIP programing 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, apply the desired
VTRIP threshold voltage to the VCC pin and tie the WP
pin to the programming voltage VP. Then write 00h to
address 03h. The stop bit of a valid write operation ini-
tiates the VTRIP programming sequence. Bring WP
LOW to complete the operation.
