MP2612ER-LF-P

Overview

The MP2612ER-LF-P is a monolithic switching charger designed for 2 or 3-cell lithium-ion battery packs. It integrates a power MOSFET and operates with an input voltage range of 9 V to 24 V, delivering a maximum charging current of 2 A. The device utilizes current control mode for fast loop response and employs two control loops for precise constant-current (CC) and constant-voltage (CV) regulation. Key electrical parameters include a VBATT accuracy of 0.75%, a fixed switching frequency of 600 kHz, and a maximum power dissipation of 2.7 W. It functions within a temperature range of -20 C to +85 C and is housed in a QFN-16 package.

Feature Summary

• Integrates internal power MOSFETs to minimize external component count
• Provides high-precision CC/CV charging via dual control loops
• Includes comprehensive protection against over-temperature and over-current conditions
• Supports battery temperature monitoring and pre-conditioning for deeply discharged cells

Applications

• Portable electronic devices powered by 2 or 3-cell lithium-ion batteries
• Consumer electronics requiring compact switching charger solutions
• Industrial equipment utilizing multi-cell battery management systems

Procurement Notes

Verify the specific suffix 'P' indicates cut-tape packaging rather than reel-only supply when ordering. Confirm RoHS compliance status through official documentation as required for your assembly process. Ensure the design accommodates the specified thermal dissipation limits given the QFN-16 package constraints. Validate that the input voltage range aligns with your system's power source specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring integrated power switches and precise charge regulation for multi-cell lithium-ion configurations. The wide input voltage range supports various power sources, while the fixed frequency simplifies compensation. Consider the thermal performance requirements due to the integrated MOSFETs and verify compatibility with the QFN-16 footprint during PCB layout. Evaluate the need for external temperature sensing if battery protection is critical.
