MAX14525ETA+T

Overview

The MAX14525ETA+T is a battery management switch IC designed for lithium-ion battery protection. It integrates four independent enable switches to control power paths within a battery system. The device operates within a supply voltage range of 2.8V to 5.5V and supports an operating temperature range from -40°C to +85°C. Packaged in an 8-WFDFN exposed pad (2x2mm) surface-mount package, it provides high-accuracy overvoltage protection and current limiting capabilities essential for safeguarding portable electronic devices.

Feature Summary

• Integrates four independent enable switches for flexible power path management
• Provides high-accuracy overvoltage protection for battery safety
• Supports lithium-ion battery chemistry applications
• Features low-profile surface-mount packaging for space-constrained designs

Applications

• Lithium-ion battery protection circuits
• Portable electronic device power management
• Embedded battery charger systems
• Power distribution networks in mobile devices

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to potential counterfeit risks. Confirm the specific suffix '+T' indicates tape-and-reel packaging if required for automated assembly. Check current lifecycle status as availability may vary by region. Ensure RoHS compliance documentation matches the specific manufacturing batch for regulatory adherence.

Selection Notes

Select this component when multiple isolated power switches are needed for battery management. Compare against single-switch alternatives if fewer channels suffice. Consider the exposed pad thermal performance for high-current applications. Verify that the 8-WFDFN footprint aligns with existing PCB layout constraints and thermal design requirements.

Part Context

This part belongs to the Maxim Integrated battery management family, focusing on protection and switching functions. It complements other PMICs by handling discrete power path control rather than complex charging algorithms. The series emphasizes reliability and compact integration for consumer electronics requiring robust battery safeguards.

Replacement Considerations

Consult official Analog Devices substitution guides for verified equivalents. Generic replacements may lack the specific four-switch configuration or accuracy levels. Validate pin compatibility and thermal characteristics before integrating alternative components into existing designs.
