MC3761PJ2HAU

Overview

The MC3761PJ2HAU is a single-cell lithium-ion/polymer battery protection IC manufactured by Mitsumi Electric Company Ltd. It integrates protection functions with an internal FET to prevent overcharging and over-discharge conditions. The device operates within a temperature range of -40°C to 85°C and utilizes a surface-mount PLP-6J package, specifically identified as a 6-XFDFN Exposed Pad configuration. This component is part of the MC3761 series and is designed for efficient battery management applications.

Feature Summary

• Integrates protection circuitry with an internal field-effect transistor for compact design
• Provides specific safeguards against overcharging and over-discharge states
• Engineered for single-cell lithium-ion and lithium-polymer battery systems

Applications

• Lithium-ion battery management systems
• Lithium-polymer battery protection circuits
• Single-cell portable electronic devices

Procurement Notes

Verify the exact package designation PLP-6J (6-XFDFN Exposed Pad) matches your PCB footprint requirements. Confirm RoHS3 compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range of -40°C to 85°C aligns with your product's thermal environment specifications before finalizing procurement decisions.

Selection Notes

Select this component when a single-chip solution for single-cell Li-ion or Li-polymer batteries is required. The integrated FET reduces external component count compared to discrete protection designs. Consider the PLP-6J package size constraints and the specified operating temperature range during system design integration to ensure compatibility with your target application's physical and thermal parameters.
