Supervisory Circuits
It is important that a processor (or programmable device) have a reliable
active RESET that is released once the power supplies and internal clock cir-
cuits have stabilized. The RESET signal should not only offer a suitable
delay, but it should also have a clean monotonic edge. Analog Devices has
a range of microprocessor supervisory ICs with different features. Features
include one or more of the following.
• Power-up reset
• Optional manual reset input
• Power low monitor
• Backup battery switching
The part number series for reset and supervisory circuits from Analog
Devices are as follows.
• ADM69x
• ADM70x
• ADM80x
• ADM1232
• ADM181x
• ADM869x
