GENERAL DESCRIPTION
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/
ADM6321/ADM6322 are supervisory circuits that monitor
power supply voltage levels and code execution integrity in
microprocessor-based systems. As well as providing power-
on reset signals, an on-chip watchdog timer can reset the
microprocessor if it fails to strobe within a preset timeout
period. A reset signal can also be asserted by an external push
button through a manual reset input. The seven parts feature
different combinations of watchdog input, manual reset input,
and output stage configuration, as shown in Table 1.

rights of third parties that may result from its use. Specifications subject to change without notice. No
license is granted by implication or otherwise under any patent or patent rights of Analog Devices.
Trademarks and registered trademarks are the property of their respective owners.
Each part is available in a choice of 26 reset threshold options
ranging from 2.5 V to 5 V in 100 mV increments. There are also
four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms
(minimum) and four watchdog timeout options of 6.3 ms, 102 ms,
1600 ms, and 25.6 sec (typical).
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/
ADM6321/ADM6322 are available in 5-lead SOT-23 packages
and typically consume only 3 μA, making them suitable for use
in low power portable applications.
