MC3651DFAAAM

Overview

The MC3651DFAAAM is a battery protection integrated circuit designed for single-cell lithium-ion and lithium-polymer batteries. Manufactured by Mitsumi Electric Company Ltd, this component integrates protection functions with an internal field-effect transistor (FET). It operates within the PLP-4E package configuration to ensure safe energy storage management.

Feature Summary

• Integrates battery protection logic with an internal FET for single-cell applications
• Compatible with lithium-ion and lithium-polymer battery chemistries
• Designed for surface-mount installation in compact electronic devices

Applications

• Single-cell lithium-ion battery protection circuits
• Lithium-polymer battery management systems
• Portable consumer electronics requiring integrated cell safety

Procurement Notes

Verify the specific suffix variant against official Mitsumi documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target battery chemistry and operating temperature range before integration into the design.

Selection Notes

Select this component for applications requiring a compact, single-chip solution for single-cell battery protection. The integrated FET reduces external component count compared to discrete protection designs.

Part Context

This part belongs to the MC3651 series of battery protection ICs from Mitsumi Electric Company Ltd. The series focuses on providing reliable overcharge and over-discharge protection for portable power sources in consumer electronics.

Replacement Considerations

Check datasheets for variants like MC3651DFBAAM or MC3651DC3AAM to verify package and functional equivalence. Substitution requires confirmation of identical protection thresholds and interface requirements.
