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.

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.
