LTC4000EUFD#TRPBF

Battery Chargers Overview

The LTC4000EUFD#TRPBF is a high-voltage, high-performance controller designed to convert externally compensated DC/DC power supplies into full-featured battery chargers. It supports input voltages from 20V to 60V and delivers up to 5.5A output current with an adjustable float voltage of 14.6V. The device integrates precise current sensing for high-current applications, NTC thermistor temperature qualification, automatic recharge, C/10 trickle charge capability, and bad battery detection. It features selectable timer or current termination modes and status indicator outputs.

Battery Chargers Feature Summary

• Converts standard DC/DC converters into complete battery charging systems
• Integrates precision current sensing for accurate high-current regulation
• Supports temperature-qualified charging via NTC thermistor interface
• Provides programmable float voltage with selectable termination methods

Battery Chargers Applications

• Lithium-ion battery charging in industrial equipment
• Power management systems requiring high-voltage input
• Battery backup units with trickle charge requirements
• Portable devices utilizing external DC/DC topologies

Battery Chargers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the component is the standalone controller IC and not a demonstration board like the DC1830B-D. Ensure compatibility with external compensation components as this is a controller, not an integrated switcher.

Battery Chargers Selection Notes

Select this part when designing a charger around an existing external DC/DC converter topology. It is suitable for applications requiring high input voltages up to 60V. Consider external MOSFETs and inductors as this is a control IC only. Verify thermal management needs for the 5.5A capability.

Battery Chargers Part Context

This component belongs to Analog Devices' battery management portfolio. It complements other chargers like the LTC4099 and LTC4162 by offering a flexible controller solution for custom power stages rather than an integrated monolithic charger.

Battery Chargers Replacement Considerations

Direct substitutes are limited due to the specific high-voltage controller architecture. Evaluate the LTC4000-1 variant for minor functional differences. No direct cross-reference is confirmed in public documentation.
