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.
