SP6330 Family: Selecting a Multi-Voltage Supervisor
2006 Sipex Corporation

Inputs to the SP6330 Family
The SP6330 family has the ability to monitor up to 4 different voltages. Two of
these inputs (V1 and V2) have precision factory-set thresholds while the
remaining two inputs (V3 and V4) are adjustable. V3 and V4 inputs allow the user
to customize two additional supply thresholds by means of an external divider.
The threshold for V3 and V4 inputs is 0.5Volts. The V1 input supplies power to
the device and will have the highest threshold for a given application; its
minimum operating voltage for is 1.8V. The factory set threshold range for V1
and V2 inputs are shown in Figure 1.

Reset Output – RST or RSTB
The reset output can be either active low or active high depending on each
device. The reset output can also be either open-drain or push-pull outputs. The
open drain output requires an external pull-up resistor to V1 for normal operation.
The output high voltage (VOH) of the reset output will be approximately equal to
the V1 input voltage.
Reset Timeout Period
The reset timeout period is a built-in time delay for the reset output. This timeout
period is activated at power up or when all monitored voltages have risen above
their respective thresholds. Reset timeout period for the SP6330 family is offered
in four different time intervals: 50ms, 100ms, 200ms and 400ms. The actual
selection of timeout period depends on the applications requirements of the
system voltage settle time. The reset timeout period is used to ensure that all
voltage rails and system clocks have stabilized prior to executing code to prevent
errors or data corruption.
