CASCADING MULTIPLE DEVICES

Multiple ADM1185 devices can be cascaded in situations where

a large number of supplies must be monitored and/or

sequenced. There are numerous configurations for

interconnecting devices. The most suitable configuration will

depend on the application. Figures 8, 9 and 10 show some

methods for cascading multiple ADM1185 devices.
