Design of fully isolated lithium-ion battery monitoring and protection system with schematic, bill of materials, assembly drawing, data sheet

SR05 SOT143 package 5V ESD electrostatic protection

Summary:

Circuit function and advantage

Lithium-ion (Li-Ion) battery packs contain a large number of battery cells that must be properly monitored to increase battery efficiency, extend battery life and ensure safety. The 6-channel AD7280A device in the circuit shown in Figure 1 acts as the primary monitor, providing accurate voltage measurement data to the System Demonstration Platform (SDP-B) evaluation board, while the 6-channel AD8280 device acts as a secondary monitor and protection system. Both devices feature a single supply wide operating voltage range of 8V to 30V and an operating temperature range of –40°C to +105°C.
