MP2617AGL-P

Overview

The MP2617AGL-P is a monolithic switching battery charger designed for single-cell lithium-ion batteries with a 4.35V maximum charge voltage. It features an input operating voltage range of 4V to 10V and supports SMD/SMT installation in a QFN-20 package. The device operates within a temperature range of -40°C to +125°C, draws a typical supply current of 3.8mA, and has a power dissipation rating of 2.6W.

Feature Summary

• Integrates synchronous buck regulation for stable system output while charging the battery
• Provides intelligent NVDC power path management to prioritize system load over battery charging
• Supports both USB and high-power DC adapter inputs with adjustable current limits
• Includes five control loops: input current limit, input voltage limit, constant charge current, battery cutoff, and thermal foldback

Applications

• Single-cell lithium-ion battery charging for tablets
• Portable electronic devices requiring integrated power path management
• Systems powered by USB or DC adapters with simultaneous load operation

Procurement Notes

Verify the specific suffix 'P' indicates cut tape packaging rather than reel when ordering. Confirm the 4.35V charge voltage specification aligns with your battery chemistry requirements. Ensure the QFN-20 footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for the latest environmental compliance and RoHS status before finalizing procurement.

Selection Notes

Select this component for applications requiring a 3A switching charger with integrated power path management. It is suitable for designs needing support for both USB and DC adapter inputs. Consider the 1.6MHz switching frequency and small QFN-20 package for space-constrained portable devices. Verify compatibility with USB2.0 and USB3.0 input specifications if used in mobile platforms.

Part Context

This part belongs to the MP2617A series from Monolithic Power Systems, which includes variants like the MP2617BGL-Z. While sharing similar architecture, the MP2617A series is specifically optimized for 4.35V single-cell lithium-ion batteries, distinguishing it from other series members that may target different voltage profiles or current ratings.

Replacement Considerations

MP2617AGL-Z is a direct substitute offering identical electrical characteristics but differs in reel packaging configuration.
