LTC4088EDE#TRPBF

Battery Chargers Overview

The LTC4088EDE#TRPBF is a high-efficiency USB PowerPath controller and Li-Ion/Polymer battery charger from Analog Devices Inc. It integrates a synchronous switching input regulator, a full-featured battery charger, and an ideal diode in a 14-lead DFN package. The device supports a 1.5A output current with a regulated 4.2V output voltage for single-cell batteries. It operates within a supply voltage range of 4.35V to 5.5V and functions reliably across a temperature range of -40°C to 85°C.

Battery Chargers Feature Summary

• Integrates a synchronous switching input regulator that automatically limits input current to optimize power usage from USB ports.
• Features an automatic charge current reduction mechanism to maintain a regulated 3.6V output during low-battery conditions.
• Includes an internal 180mΩ ideal diode and external controller capability to ensure seamless power path switching.

Battery Chargers Applications

• USB-powered portable electronic devices requiring integrated charging and power management
• Battery-operated systems utilizing lithium-ion or lithium-polymer cells
• Applications with constrained thermal environments needing efficient power sharing

Battery Chargers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when placing orders. Confirm the DEDE variant corresponds to the standard DFN package dimensions. Ensure compatibility with RoHS compliance requirements for your manufacturing process. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Battery Chargers Selection Notes

Select this component for designs requiring simultaneous battery charging and system power distribution from a USB source. The LTC4088-2 variant powers up with the charger enabled, which may suit applications needing immediate battery support. Consider the 1.5A output limit and 4.2V regulation when sizing external components. Evaluate thermal performance given the compact DFN footprint in enclosed enclosures.

Battery Chargers Part Context

This part belongs to the LTC4088 family of high-efficiency battery chargers designed specifically for USB applications. It distinguishes itself by combining power path management with charging functionality in a single IC. The family addresses the need for optimal power utilization from limited USB sources while maintaining system uptime through intelligent power sharing.
