LTC4162IUFD-FADM#TRPBF

Battery Management Overview

The LTC4162IUFD-FADM#TRPBF is a monolithic synchronous step-down switching battery charger and PowerPath manager designed for lithium iron phosphate (LiFePO4) batteries. It supports input voltages from 4.5 V to 35 V and delivers up to 3.2 A output current. The device integrates maximum power point tracking (MPPT) for solar applications and manages power distribution between multiple input sources, including wall adapters, backplanes, and solar panels. Packaged in a 28-lead QFN with an exposed pad, it operates within a temperature range of -40°C to +125°C.

Battery Management Feature Summary

• Integrates maximum power point tracking for efficient solar energy harvesting
• Manages seamless power distribution between multiple input sources and the battery
• Supports advanced charging profiles specifically optimized for LiFePO4 chemistry

Battery Management Applications

• Solar-powered portable electronics requiring MPPT functionality
• USB Power Delivery charging systems for LiFePO4 devices
• Industrial equipment utilizing backplane power inputs
• Wall adapter powered consumer devices with LiFePO4 batteries

Battery Management Procurement Notes

Verify the specific suffix FADM confirms the intended LiFePO4 configuration and MPPT settings against the official datasheet. Confirm package type and reel specifications match design requirements. Check availability status as supply may be limited or subject to factory order constraints. Ensure compatibility with system voltage ranges and thermal management needs.

Battery Management Selection Notes

Select this component when designing systems that require integrated MPPT for solar inputs alongside standard AC/DC or USB power sources. It is suitable for applications needing precise LiFePO4 charging management with high efficiency. Consider the 28-lead QFN package for space-constrained designs requiring robust thermal performance and multiple input handling capabilities.

Battery Management Part Context

This part belongs to the LTC4162 family of battery chargers, which are engineered for versatile input source management. The IUFD variant indicates an industrial temperature rating and specific packaging. The FADM suffix denotes configuration for LiFePO4 batteries with integrated MPPT features, distinguishing it from variants supporting Lithium-ion or Lead-Acid chemistries.

Battery Management Replacement Considerations

Direct substitutes include other LTC4162 variants such as LTC4162EUFD-FADM#TRPBF for similar LiFePO4 applications. Cross-reference suffixes carefully as they determine battery chemistry support and feature sets like MPPT integration. Verify pinout and thermal pad configurations remain identical for board-level replacement.
