It operates within a supply voltage range of 4 V to 55 V and features an SSOP-44 surface-mount package. The device supports up to twelve series-connected cells, providing cell voltage monitoring with a maximum output voltage of 5 V and an output current capability of 8 mA. It functions within an industrial temperature range from -40°C to +85°C, consuming a typical operating supply current of 780 µA.

Feature Summary

• Monitors up to twelve series-connected battery cells in high-voltage stacks
• Enables passive balancing through selective resistive loading on individual cells
• Supports daisy-chain communication to link multiple devices for extended stacks

Applications

• Lithium-ion battery stack monitoring systems
• Electric vehicle battery management applications
• Industrial energy storage system protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm the specific suffix matches the required thermal grade and packaging configuration. Request original datasheets and material compliance documentation prior to integration. Validate that the SSOP-44 footprint aligns with design constraints. Ensure supply chain stability given potential restricted distribution periods.

Selection Notes

Select this variant when an industrial temperature rating of -40°C to +85°C is required for the application environment. The IG suffix denotes the specific thermal performance class compared to other family members. Consider the SSOP-44 package dimensions for PCB layout constraints. Evaluate the 780 µA supply current against system power budgets. Verify compatibility with existing daisy-chain communication protocols for multi-device expansion.
