GENERAL DESCRIPTION The ADM8611/ADM8616/ADM8617/ADM8618 are supervisory circuits which monitor power supply voltage levels and code execution integrity in microprocessor-based systems. A power-on-reset signal is generated when the supply voltage rises to a preset threshold level. The ADM8611’s debounced www.DataSheet4U.com manual reset input can be used to initiate a reset by means of an external push-button or logic signal. The ADM8616–ADM8618 have an on-chip watchdog timer which can reset the microprocessor if it fails to strobe within a preset timeout period. Each part is available in a choice of the following 9 reset threshold options: 1.58V, 1.67V, 2.19V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V and 4.63V. The re.
