Revision 1.8

1 General Description
The AS1907/AS1908/AS1909 mcroprocessor supervisory circuits
are ideal for monitoring the supply voltage of digital systems and
mcroprocessors.
The devices are designed to initiate a reset if the supply voltage goes
below a predefined threshold. The duration of the reset is either 1.5,
30, or 150ms (typ.) after the supply voltage has risen above the pre-
set threshold
(see Ordering Information on page 9)
.
The devices are available as the standard products listed in
Table 1
.
The reset thresholds are factory-set between 1.6 and 2.5V in steps
of approximately 100mV
(see Table 5 on page 7)
.
The devices exhibit excellent reliability, and can reduce systemcosts
by elimnating the need for external components. The extremely low
current consumption makes the devices ideal for use in portable
applications.
The integrated reset comparator was specifically designed to ignore
fast transients on V
CC
.
The devices are available in a 3-pin SOT23 package.
