GENERAL DESCRIPTION
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/
ADM6321/ADM6322 are supervisory circuits which 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 means of 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.

Supervisory Circuits with Watchdog
and Manual Reset in 5-Lead SOT-23
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
(min) and four watchdog timeout options of 6.3 ms, 102 ms,
1600 ms, and 25.6s (typ).
The ADM6316-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.
