MAX8682ETM+T

Overview

The MAX8682ETM+T is a power management integrated circuit designed for single-cell lithium-ion battery systems. It integrates a linear charger, a high-efficiency synchronous step-down DC-DC converter, and a low-dropout regulator. The device supports input voltages up to 5.5V and provides regulated outputs for system operation. Packaged in a 48-pin TQFN with exposed pad, it offers comprehensive protection features including thermal regulation and current limiting for portable electronic applications.

Feature Summary

• Integrates a linear battery charger with a synchronous buck converter and an LDO regulator within a single chip
• Supports single-cell lithium-ion or lithium-polymer battery chemistries
• Includes hardware fault protection mechanisms such as thermal shutdown and charge current monitoring

Applications

• Portable medical devices requiring reliable battery charging and power sequencing
• Handheld consumer electronics utilizing single-cell lithium batteries
• IoT sensors and wearables needing compact power management solutions

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the standard tube variant. Confirm RoHS compliance status through official documentation. Check current lifecycle status as availability may be limited. Ensure the supplier provides valid traceability for Analog Devices components.

Selection Notes

Select this component when space constraints require integrating charging and power conversion functions. It is suitable for designs powered by USB or wall adapters. Consider the thermal performance of the 48-TQFN package for high-current applications. Verify that the required output currents align with the internal regulator capabilities.
