DESCRIPTION
The DS1836 MicroManager performs three vital system functions. First, a precision temperature-
compensated reference and comparator circuit monitor the status of the voltage on V
CC
and when an out-
of-tolerance condition is detected, an internal power-fail signal is generated that forces the reset active. If
V
CC
continues to degrade, it switches to the battery supply when V
CC
drops below 3.8V (2.6V for 3.3V
versions). When V
CC
exceeds 3.9V (2.8V for 3.3V 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 1.25V.
