Fully Isolated Lithium Ion Battery Monitoring and Protection System

Lithium ion (Li-Ion) battery stacks contain a large number of individual cells that must be monitored correctly in order to enhance the battery efficiency, prolong the battery life and ensure safety. The 6-channel AD7280A devices in Circuit act as the primary monitor providing accurate voltage measurement data to the System Demonstration Platform (SDP-B) evaluation board and the 6-channel AD8280 devices act as the secondary monitor and protection system. Both devices can operate from a single wide supply range of 8 V to 30 V and operate over the industrial temperature range of -40C to +105C
