Electrical regulator health monitor circuit systems and methods

摘要

Systems and methods for regulating input to a sensor. A circuit receives an unregulated voltage signal and a reduced version of the unregulated voltage signal. These signals are regulated by separate regulators then compared. If the difference between the two regulated signals is greater than a threshold amount then no voltage signal is sent to an attached sensor. If the difference between the two regulated signals is less than a threshold amount then a regulated voltage signal is sent to the sensor.
