DESCRIPTION
The DS1813 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.
The DS1813 also monitors a pushbutton on the reset
output. If the reset line is pulled low, a reset is generated
upon release and will be held in reset output low for typi-
cally 150 ms.
