7.1 Application Information

The UCD91160 device can be used to sequence and monitor up to 16 voltage rails, and margin up to 8 voltage rails. Up to four UCD91160 devices can be cascaded to allow the user to monitor up to 64 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 Sequencer Studio software provided by TI. No coding skill is required.
