LTC4088EDE-1#TRPBF

Battery Chargers Overview

The LTC4088EDE-1#TRPBF is a high-efficiency USB PowerPath controller and Li-Ion/Polymer battery charger manufactured by Analog Devices Inc. It integrates a synchronous switching input regulator, a full-featured battery charger, and an ideal diode within a low-profile 14-Lead 4mm x 3mm x 0.75mm DFN surface mount package. Designed for USB applications, the device automatically limits input current to 100mA, 500mA, or 1A via logic control. The LTC4088-1 variant powers up with the charger off. The switching input stage manages power sharing between the application circuit and the battery charger, providing regulated output voltage.

Battery Chargers Feature Summary

• Integrates a synchronous switching input regulator that optimizes limited USB port power for simultaneous battery charging and system operation
• Features automatic charge current reduction to maintain a regulated 3.6V output during low-battery conditions, easing thermal constraints
• Includes an internal 180mΩ ideal diode and external ideal diode controller capability for seamless low-loss power path management

Battery Chargers Applications

• USB-powered portable electronic devices requiring integrated power management
• Applications utilizing Li-Ion or Li-Polymer batteries in constrained thermal environments
• Systems requiring automatic input current limiting from USB ports

Battery Chargers Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct startup behavior and pinout compatibility. Confirm that the 14-lead DFN package dimensions align with your PCB footprint requirements. Cross-reference the datasheet revision history to validate electrical characteristics and operational parameters before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component when designing USB-powered systems that require efficient power distribution between the host source and the battery. The LTC4088-1 is appropriate for designs where the charger should remain inactive upon initial power-up. Consider the integrated switching regulator for improved efficiency compared to linear solutions in space-constrained applications.

Battery Chargers Part Context

This component belongs to the LTC4088 family of high-efficiency battery chargers and USB power managers. It shares functional similarities with the LTC4088-2, which differs primarily in its default startup state regarding the charger enablement. The device is part of Analog Devices' portfolio focused on optimizing power delivery in mobile and portable electronics.

Battery Chargers Replacement Considerations

The LTC4088EDE-2#TRPBF serves as a direct functional substitute within the same package, differing only in the default charger startup state.
