App note: Monitor negative power supplies

Sunday, March 20th, 2011

Precision circuit monitors  negative-supply threshold: Using an IC (MAX971) that includes an open-drain comparator and a precision 1% voltage reference, this circuit monitors the magnitude of a negative supply voltage and provides a digital warning of fault conditions. To monitor multiple negative voltages, use the MAX974, which includes four comparators....
