GENERAL DESCRIPTION

The ADM9264 is a Quad Supply Monitor IC which simultaneously monitors four separate power supply voltages and outputs error signals if any of the supply voltages go out of limits. It is designed for PC supply monitoring but can be used on any system where multiple power supplies require monitoring. The error output signals are available individually and also gated into a common output - PWROK. Auxiliary inputs ERRX, ERRY are provided which are also gated into the main PWROK signal. These inputs allow signals from other monitoring circuits (for example temperature sensor, alarm, etc.) to be linked into the ADM9264.
