Monitoring circuit for computer system current supply has selection circuit, current-limiting comparison circuit providing various modes enabling loads to be compared by current-limiting comparison circuit individually or in integrated form

摘要

The circuit has a power output stage (10) with a number of sets of power outputs for operating a number of loads (40) and a current-limiting comparison circuit (30) between the loads and power outputs to determine whether the power output of the output stage for operating a load is in a normal state or a false state. A selection circuit (20) and the current-limiting comparison circuit provide one to one, one to many, many to many and many to one modes to enable the loads to be compared by the current-limiting comparison circuit individually or in integrated form.
