MP2612ER-LF-Z

Overview

The MP2612ER-LF-Z is a monolithic switch-mode charger designed for 2 or 3-cell lithium-ion battery packs. It integrates a power MOSFET and operates from an input voltage range of 9 V to 24 V, delivering a programmable charging current up to 2 A. The device provides precise constant-current (CC) and constant-voltage (CV) regulation with a battery voltage accuracy of 0.75%. It utilizes a fixed 600 kHz switching frequency and achieves efficiencies up to 90%. The component is housed in a 16-pin QFN package and supports an operating temperature range from -20°C to +85°C.

Feature Summary

Integrates internal power MOSFETs to minimize external component count
Provides high-precision CC/CV charging control via dual feedback loops
Includes comprehensive protection against over-temperature and over-current conditions

Applications

Portable electronic devices powered by multi-cell lithium-ion batteries
Battery management systems requiring integrated charge management
Consumer electronics utilizing 2S or 3S battery configurations

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before finalizing any design implementation. Confirm that the specific QFN-16 package variant matches your PCB footprint requirements. Ensure compatibility with the specified 9 V to 24 V input range for your target application environment.

Selection Notes

Select this component when designing for 2 or 3 series lithium-ion cells requiring up to 2 A charging capability. It is suitable for applications needing wide input voltage tolerance and integrated power switching. Consider thermal dissipation capabilities within the QFN-16 package for high-load scenarios.

Part Context

This part belongs to the MPS MP2612 series of battery chargers. It shares architectural similarities with other members like the MP26123 but differs in specific electrical ratings and pinout configurations. The series focuses on compact, high-efficiency charging solutions for portable equipment.
