ABSTRACT:
A power supply detection circuit monitors an input voltage and generates a magnitude signal representative of a supply voltage magnitude. Timing signals are generated relative to a transient condition associated with connection to an input voltage. A data store receives timing signals and stores the magnitude signal at a timing interval so that the stored magnitude signal is representative of a predetermined power supply magnitude. The stored magnitude signal is used to automatically configure power protection circuitry and monitoring circuitry.
