MAX1552ETE

Overview

The MAX1552ETE is a specialized power management integrated circuit (PMIC) designed for low-cost personal digital assistants and portable cellular devices. It operates from a single-cell lithium-ion battery source. The component integrates multiple power supply functions into a compact 16-pin WQFN package with an exposed pad, facilitating surface-mount installation. It supports system power sequencing and regulation requirements typical of handheld communication equipment.

Feature Summary

• Integrates complete power management solution for portable applications
• Operates directly from single-cell lithium-ion battery sources
• Designed specifically for cost-sensitive personal digital assistant architectures

Applications

• Personal Digital Assistants (PDAs)
• Portable cellular phones
• Handheld communication devices

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details through official manufacturer documentation before integration. Ensure the specific suffix matches design requirements. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with existing designs.

Selection Notes

Select this PMIC when designing single-cell lithium-ion powered portable systems requiring integrated power sequencing. It is suitable for applications prioritizing board space efficiency and reduced component count. Verify that the operating voltage range and current capabilities align with the target device's subsystem requirements. Consider the thermal performance of the exposed pad package for heat dissipation.

Part Context

This component belongs to the Maxim Integrated portfolio, now part of Analog Devices Inc. It represents a specialized class of power management ICs tailored for the mobile consumer electronics market during the era of early PDAs and feature phones. The device consolidates multiple power rails into a single chip to simplify PCB layout and reduce overall system cost.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the specialized nature of this legacy PMIC and potential discontinuation status, direct replacements may require functional equivalence analysis rather than simple pin-to-pin substitution. Consult official manufacturer resources for end-of-life notifications and recommended alternatives.
