MAX8982MEWO+T

Overview

The MAX8982MEWO+T is a specialized power management integrated circuit (PMIC) designed for cellular baseband processors. It integrates ten output regulators to support complex multi-voltage requirements in mobile communication devices. The device features a 42-wafer level package (WLP) for compact integration. Key outputs include dedicated supplies for the core, I/O, and analog sections of the baseband processor, ensuring stable operation across varying load conditions.

Feature Summary

• Integrates multiple voltage regulators into a single compact solution
• Optimized for powering cellular baseband processors
• Utilizes a small form factor wafer level package

Applications

• 3G/4G cellular baseband processor power supply
• Mobile phone mainboard power management
• Wireless communication module voltage regulation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot codes and date codes against current production status. Ensure compliance with RoHS directives as indicated by the suffix. Request original datasheets and test reports to validate performance specifications before integration into design.

Selection Notes

Evaluate thermal dissipation requirements within the 42-WLP footprint. Verify input voltage ranges match the system battery profile. Check compatibility with baseband processor startup sequencing requirements. Consider electromagnetic interference characteristics relative to nearby RF components. Assess availability given potential end-of-life status for this specific variant.

Part Context

This component belongs to the Maxim Integrated PMIC family targeting mobile communications. It replaces discrete regulator solutions to save board space. The MAX8982 series provides integrated power management for high-performance baseband chips. Analog Devices acquired Maxim Integrated, continuing support for these legacy parts.

Replacement Considerations

Check for MAX8982 variants with different package options such as MAX8982MEWO+ without tape/reel suffix if bulk packaging is preferred. Verify functional pin-to-pin compatibility with alternative PMICs from the same family before substitution.
