MCP73124T-2JAI/MF

Overview

The MCP73124T-2JAI/MF is a linear Li-Ion/Li-Polymer battery charger controller manufactured by Microchip Technology. It is housed in a 10-VFDFN package with an exposed pad, specifically identified as a 10-DFN (3x3) supplier device package. This integrated circuit functions as a dedicated controller for managing the charging cycles of lithium-ion and lithium-polymer cells within portable electronic devices.

Feature Summary

• Provides precise control over the charging process for lithium-based battery chemistries
• Integrates thermal regulation to manage heat dissipation during high-current operation
• Supports standard charging profiles including constant current and constant voltage phases

Applications

• Portable consumer electronics requiring safe lithium battery management
• Mobile communication devices utilizing Li-Ion or Li-Polymer power sources
• Wearable technology with compact power supply requirements

Procurement Notes

Verify the specific suffix JAI against the manufacturer's official datasheet to confirm temperature range and quality grade specifications. Ensure the 10-DFN (3x3) footprint matches the target PCB layout, paying close attention to the exposed pad thermal connection requirements for proper heat sinking and electrical grounding.

Selection Notes

Select this component when designing systems that require a dedicated controller rather than a fully integrated charger IC. The choice depends on the need for external power FETs to handle higher currents or specific system architectures. Confirm compatibility with the target battery cell chemistry and required charge termination methods before integration into the design.

Part Context

This part belongs to the MCP73124 series of battery charger controllers from Microchip Technology. The series is designed to offer flexibility in power management solutions for various portable applications. The T-2JAI/MF designation indicates specific packaging and environmental classifications within this product line.

Replacement Considerations

Consult Microchip's official cross-reference documentation for verified substitutes. Direct replacements must maintain the 10-DFN package and compatible Li-Ion/Li-Poly control logic.
