DESCRIPTION
The DS1233M EconoReset uses a precision tempera-
ture compensated 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
(low) state. When V
CC
returns to an in-tolerance condi-
tion, the reset signal is kept in the active state for ap-
proximately 350 ms to allow the power supply and pro-
cessor to stabilize.
