Power regulation for redundant battery supplies.

摘要

A regulator circuit supplies a regulated low, DC voltage that is derived from an unregulated voltage provided by a pair of redundant batteries. The regulator circuit comprises regulation control that responds to a feedback signal developed from monitoring the regulated voltage to maintain the regulated voltage at a desired level. Battery monitors supervise the voltage levels of the batteries used, and shut down the regulator when the battery voltages drop below a predetermined voltage level to preserve battery life. <IMAGE>
