MP26101DR-LF-P

Battery Chargers Overview

The MP26101DR-LF-P is a monolithic switching charger designed for 1 to 2 series lithium-ion battery packs. It integrates power MOSFETs and operates within a wide input voltage range of 5 V to 24 V, delivering a maximum charge current of 2 A. The device supports a full-charge voltage of 4.1 V per cell, resulting in an 8.2 V output for dual-cell configurations. It utilizes a fixed 1.1 MHz switching frequency and features a QFN-16 package with a thermal pad. The IC includes programmable charge termination timers and offers protection against over-temperature and over-current conditions.

Battery Chargers Feature Summary

• Integrates internal power MOSFETs to minimize external component count
• Provides high-efficiency constant-current and constant-voltage charging control
• Includes comprehensive safety features such as thermal regulation and cycle-by-cycle current limiting

Battery Chargers Applications

• Portable electronic devices requiring compact power management solutions
• Consumer electronics utilizing single or dual-cell lithium-ion battery systems
• Industrial equipment needing reliable battery charging from wide-range DC sources

Battery Chargers Procurement Notes

Verify the suffix 'P' indicates cut-tape packaging rather than reel packaging when ordering. Confirm that the specific lot date codes meet project requirements due to potential supply chain variations. Ensure compatibility with existing PCB footprints for the QFN-16 package before finalizing procurement decisions.

Battery Chargers Selection Notes

Select this component for designs requiring integrated power switches and support for up to two series cells. It is suitable for applications where space constraints limit the use of discrete MOSFETs. Consider the 5 V to 24 V input range for flexibility in adapter selection. Evaluate thermal performance based on the 2.7 W power dissipation rating under expected load conditions.

Battery Chargers Part Context

This part belongs to the MP26101 family of battery chargers from Monolithic Power Systems. It shares core electrical specifications with the MP26101DR-LF-Z variant, differing primarily in packaging format. The family is designed for efficient charging of lithium-ion batteries in portable applications.

Battery Chargers Replacement Considerations

MP26101DR-LF-Z is a parameter-equivalent alternative available from the same manufacturer. Verify that the packaging difference does not impact automated assembly processes.
