LT8584IFE#TRPBF

Battery Management Overview

The LT8584IFE#TRPBF is a monolithic flyback DC/DC converter designed for active cell balancing in high-voltage battery stacks. It features an integrated 6A/50V power switch and delivers a typical average discharge current of 2.5A. The device operates from the battery it discharges, eliminating complex bias circuits. It supports isolation to return charge to the stack top, any combination within the stack, or a 12V battery. The industrial temperature grade version ensures operation within a -40°C to 125°C junction temperature range.

Battery Management Feature Summary

• Active cell balancing with high efficiency to maximize usable battery capacity
• Integrated 6A/50V power switch enabling compact application circuitry
• Seamless integration with LTC680x series battery monitors without additional software
• Ultra-low static current consumption when disabled

Battery Management Applications

• Electric vehicle and hybrid electric vehicle battery management systems
• Fault-safe power supply systems
• Energy storage systems requiring high-voltage stack balancing

Battery Management Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging versus tube variants. Confirm the IFE designation corresponds to the industrial temperature range specifications required for your design environment. Ensure compatibility with the intended LTC680x monitor family for seamless system integration.

Battery Management Selection Notes

Select this component for applications requiring active rather than passive balancing to improve total pack capacity utilization. The industrial grade rating suits environments demanding reliability between -40°C and 125°C junction temperatures. Consider parallel configurations if higher balancing currents exceed the single-device 2.5A capability.

Battery Management Part Context

This part belongs to the LT8584 family of active cell balancers from Analog Devices. It complements the LTC680x series of battery stack monitors to provide comprehensive battery management solutions. The family addresses the limitations of passive balancing by redistributing energy from stronger cells to weaker ones during discharge cycles.
