MP2617BGL-P

Overview

The MP2617BGL-P is a single-cell lithium-ion switching charger from Monolithic Power Systems, designed for portable devices. It features an input voltage range of 4V to 10V and supports a maximum output current of 3A with a fixed output voltage of 4.5V. The device operates within a temperature range of -40°C to +125°C TJ and has a quiescent supply current of 3.8mA. It dissipates up to 2.6W of power and is housed in a QFN-20 package.

Feature Summary

• Integrates NVDC smart power path management to prioritize system load while charging the battery
• Supports USB 2.0/3.0 specifications with adjustable input current limits via logic pins
• Includes five control loops: input current limit, input voltage limit, constant charge current, full voltage control, and thermal foldback
• Provides battery temperature monitoring and chip temperature regulation for safety

Applications

• Single-cell lithium-ion battery charging for tablets
• Portable electronic device power management
• USB-powered gadget charging systems
• High-power DC adapter charging applications

Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the QFN-20 footprint matches your PCB layout requirements. Check for any recent design changes or obsolescence notices directly from Monolithic Power Systems before finalizing procurement plans.

Selection Notes

Select this component for applications requiring integrated power path management between USB and AC adapters. It is suitable for designs needing programmable input current limits to comply with USB standards. Consider the QFN-20 package size constraints and thermal dissipation capabilities relative to the 2.6W power rating. Verify compatibility with 4.2V single-cell lithium-ion battery chemistries.

Part Context

This part belongs to the MP2617B series of switching chargers. It is functionally similar to the MP2617AGL-P but optimized for 4.2V batteries rather than 4.35V variants. The MP2617BGL-Z serves as a reel-packaged alternative within the same family. Both share identical electrical characteristics and pinouts for direct interchangeability in compatible designs.

Replacement Considerations

MP2617BGL-Z is a parameter-equivalent replacement offering the same functionality in a reel package format.
