GENERAL DESCRIPTION

The ADM6384 is a supervisory circuit that monitors power supply voltage levels in microprocessor-based systems. A power-on reset signal is generated when the supply voltage rises to a preset threshold level. The debounced manual reset input of the ADM6384 can be used to initiate a reset by means of an external push button or logic signal.
