MC3651DC3AAM

Overview

The MC3651DC3AAM is a single-cell lithium-ion or lithium-polymer battery protection integrated circuit manufactured by Mitsumi Electric Company Ltd. Designed for surface-mount applications, this component integrates protection functions with an internal field-effect transistor (FET). It ensures safe operation of 1-cell battery packs by monitoring voltage and current conditions to prevent overcharge, over-discharge, and overcurrent scenarios.

Feature Summary

• Integrates battery protection logic with an internal FET for compact design
• Supports surface-mount technology for automated assembly
• Compatible with lithium-ion and lithium-polymer cell chemistries

Applications

• Single-cell lithium-ion battery pack protection
• Lithium-polymer battery management systems
• Portable electronic device power safety circuits

Procurement Notes

Verify the specific suffix DC3AAM against official Mitsumi documentation to confirm pinout and electrical characteristics. Ensure compliance with RoHS3 standards if required by your manufacturing process. Confirm moisture sensitivity level (MSL) handling procedures during storage and reflow soldering to maintain component integrity.

Selection Notes

Select this part when a compact, single-chip solution is needed for 1-cell Li-ion or Li-Po batteries. The integrated FET reduces external component count compared to discrete protection designs. Verify that the package type and thermal requirements align with the target PCB layout and operating environment constraints.

Part Context

This component belongs to the MC3 series of battery protection ICs from Mitsumi Electric. These devices are engineered for high reliability in consumer electronics and portable devices. The MC3651 variant specifically targets single-cell applications, offering a balance of protection accuracy and integration density within a small footprint.

Replacement Considerations

Check for direct substitutes with identical pinouts and protection thresholds. Verify compatibility with existing BOM components. Ensure any replacement maintains the same MSL rating and RoHS compliance status to avoid supply chain or regulatory issues.
