validate and test their design implementation to confirm system functionality.
9.1 Application Information
The UCD90320 device can be used to sequence, monitor up to 32 rails and margin up to 24 voltage rails. With
the cascading feature, up to four UCD90320 devices can manage up to 128 rails and record synchronized fault
responses. Typical applications include automatic test equipment, telecommunication and networking equipment,
servers and storage systems. Device configuration can be performed using the Fusion Digital Power Designer
software provided by TI. No coding skill is required.
9.2 Typical Application
Figure 38 shows a simplified system diagram. For simplification, this diagram shows only three rails, but each
UCD90320 device can manage up to 32 rails.
