UCD90910: UCD90910

Part Number: UCD90910


We are using UCD 90910 in one of our application for Monitoring various power rails and Power Sequencing those power rails.

Active High signal from CPLD device is connected to UCD90910 (Pin No. 41- PWM4/ GPI4). When UCD gets High on this pin, it should turn OFF all the power rails.

Please let us know what are the ways to do it in Fusion Digital Power Designer.
