... Controllers Intelligent Instruments Network Systems GENERAL DESCRIPTION The ADM9264 is a Quad Supply Monitor IC which simulta- neously monitors four separate power supply voltages and out- puts error signals if any of the supply voltages go out of limits designed for PC supply monitoring but can be used on any system where multiple power supplies require monitor- ing ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADM9264 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... ADM9264 APPLICATIONS A typical application of the ADM9264 is shown in Figure 23. The analog inputs SU1 to SU4 are connected to the four power supply outputs of a system to monitor the supply voltages. One of the digital inputs, ERRY, is connected to a temperature sensor such as the TMP01 or AD22105. The trip point of the overtemperature comparator is set by R goes low when the temperature exceeds safe limits ...
