LTC4098EPDC-1

Battery Management Overview

The LTC4098EPDC-1 is a high-efficiency USB PowerPath controller and full-featured Li-Ion/Polymer battery charger manufactured by Analog Devices Inc. It seamlessly manages power distribution from multiple sources, including USB, wall adapters, automotive supplies, Firewire, or other high-voltage DC/DC converters, alongside a Li-Ion or Li-Polymer battery. The device features a switching regulator that automatically limits input current for USB compatibility and interfaces with an external switching regulator for higher voltage applications. It supports input supplies ranging from 5V to as high as 38V.

Battery Management Feature Summary

• Seamlessly manages power distribution from multiple sources including USB, wall adapter, automotive, Firewire, or other high voltage DC/DC converters, and a Li-Ion/Polymer battery.
• Switching regulator automatically limits input current for USB compatibility and interfaces with an external switching regulator for automotive and other high voltage applications.
• Bat-Track optimized charging provides maximum power to the application and reduced heat in high power density applications.
• Overvoltage protection circuit guards against high voltage damage on the VBUS pin using only two external components.

Battery Management Applications

• High efficiency USB power path controllers
• Full-featured Li-Ion/Polymer battery chargers
• Automotive battery management systems
• Portable devices requiring multi-source power management

Battery Management Procurement Notes

Verify the specific suffix 'EPDC-1' against official Analog Devices documentation to confirm package type and temperature range. Ensure the selected variant matches the required battery chemistry (Li-Ion/Polymer) and input voltage specifications. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity, as supply status may vary.

Battery Management Selection Notes

Select this component when designing systems requiring seamless power path management between USB and auxiliary high-voltage sources. It is suitable for applications needing Bat-Track optimization to maximize available power while minimizing thermal dissipation. Consider the external switching regulator interface if operating voltages exceed standard USB levels up to 38V.

Battery Management Part Context

The LTC4098 series includes variants such as LTC4098EUDC#PBF and LTC4098EUDC-1#PBF, which are Li-Ion/Polymer chargers in QFN packages. The EPDC suffix typically denotes a specific package configuration, such as UTQFN, distinct from the UDC QFN variant. Evaluation boards like DC1303A are associated with the LTC4098 family for prototyping purposes.
