A circuit that monitors multiple supply voltages, supply currents and temperatures of a fault-tolerant system is described. The heart of the circuit is the LTC1392, an 8-pin system monitor.
Fault-tolerant systems ensure their users uninterrupted service and prevent data loss through acquisition of accurate supply voltage, load current and temperature information. By comparing this information to predetermined operating profiles, the system decides if the measured data is within nominal ranges or if a fault condition is looming. If a fault condition is imminent, the system takes corrective ...
