Precision Circuit Monitors Negative-Supply Thresholds



关键词: negative supply voltage, multi-rail systems, comparators, voltage references 


Abstract: 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.
