DESCRIPTION
The DS1836 MicroManager performs three vital system
functions. First a precision temperature compensated
reference and comparator circuit monitors the status of
the voltage on V
CC
and when an out–of–tolerance
condition is detected, an internal power fail signal is
generated which forces the reset active. If V
CC
contin-
ues to degrade it switches to the battery supply when
V
CC
drops below 3.8 volts (2.6 volts for 3.3 volt ver-
sions). When V
CC
exceeds 3.9 volts (2.8 volts for 3.3
volt versions); V
OUT
will again be supplied from V
CC
.
Reset will remain active for 350 ms after V
CC
returns to
an in–tolerance condition.
Lastly, the DS1836 supports a sense input that sends a
non–maskable interrupt whenever the sense input
drops below 1.25 volts.
