GENERAL DESCRIPTION
The ADM682x 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 means of an
external push-button through a manual reset input. The parts
feature different combinations of watchdog input and manual
reset input and output stage configurations, as shown in Table 1.
Each part is available in nine reset threshold options, ranging
from 1.58 V to 4.63 V. The reset and watchdog timeout periods
are fixed at 140 ms (min) and 1.6 sec (typ), respectively.
The ADM682x are available in 5-lead SOT-23 packages and
typically consume only 7 μA, making them suitable for use in
low power, portable applications.
