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 depends on the application. Figure 23 and
Figure 24 show two methods for cascading multiple ADM1185 devices.
