DESCRIPTION
The DS1812 EconoReset uses a precision temperature
reference and comparator circuit to monitor the status of
the power supply (V
CC
). When an out–of–tolerance
condition is detected, an internal power–fail signal is
generated which forces reset to the active state. When
V
CC
returns to an in–tolerance condition, the reset sig-
nal is kept in the active state for approximately 150 ms to
allow the power supply and processor to stabilize.
