MP26101DR-LF-Z

Overview

The MP26101DR-LF-Z is a switching Li-ion battery charger from Monolithic Power Systems designed for 1 to 2 cell configurations. It supports an input voltage range of 5 V to 24 V and delivers a maximum charging current of 2 A. The device provides a regulated output voltage of 8.2 V, suitable for series-connected lithium cells. It operates within a junction temperature range up to +125°C and features a low quiescent supply current of 2 mA. The component is housed in a 16-QFN (4x4 mm) package with exposed pad for surface mount installation.

Feature Summary

• Integrates power MOSFETs for high-efficiency switching operation
• Supports wide input voltage range for adapter compatibility
• Includes thermal regulation and battery temperature monitoring

Applications

• Portable electronic devices requiring 1-2 cell lithium battery charging
• Consumer electronics powered by USB or wall adapters
• Industrial equipment with 24V input capabilities

Procurement Notes

Verify the suffix Z indicates RoHS compliance and halogen-free status. Confirm the DR variant specifies the specific tape and reel packaging format required for automated assembly. Ensure the QFN-16 footprint matches the PCB design guidelines provided in the official datasheet to guarantee proper thermal dissipation and electrical connection.

Selection Notes

Select this component when designing systems requiring a compact solution for 1 or 2 series lithium cells. It is appropriate for applications needing up to 2A charging current from inputs ranging between 5V and 24V. Consider the 16-QFN package size constraints and the need for external sense resistors if precise current programming is required beyond standard settings.

Part Context

This part belongs to the MP26101 family of battery chargers. It shares functional similarities with other MPS parts like the MP2610 but offers specific input voltage and cell count optimizations. The DR-LF-Z designation identifies it as a lead-free, RoHS-compliant version in a specific reel packaging configuration distinct from cut-tape alternatives.

Replacement Considerations

MP26101DR-LF-P is listed as a parameter equivalent alternative offering different packaging options such as cut tape.
