MP2617BGL-Z

Overview

The MP2617BGL-Z is a monolithic switching charger for single-cell lithium-ion batteries with an output voltage of 4.2V. It operates within a supply voltage range of 4V to 10V and features a USB interface. The device supports programmable constant current charging and includes a built-in timer. It utilizes a 20-PowerTFQFN (20-QFN 3x4) surface-mount package. The component functions across a junction temperature range of -40°C to 125°C and incorporates over-temperature fault protection.

Feature Summary

• Integrates NVDC power path management to support simultaneous system load powering and battery charging
• Supports both USB and high-power DC adapter inputs with adjustable input current limits
• Includes five control loops: input current limit, input voltage limit, constant charge current, full charge voltage control, and thermal foldback

Applications

• Single-cell lithium-ion battery charging in tablets
• Portable electronic devices requiring integrated power path management
• USB-powered consumer electronics systems

Procurement Notes

Verify the specific suffix Z against official Monolithic Power Systems documentation to confirm compliance with RoHS3 standards and lead-free specifications. Confirm that the 20-QFN package dimensions match the target PCB footprint requirements. Ensure the selected variant aligns with the required 4.2V output specification for standard lithium-ion cells rather than high-voltage variants.

Selection Notes

Select this component when designing for single-cell lithium-ion applications requiring up to 10V input. It is suitable for designs needing intelligent power path management to prioritize system loads during charging. Verify compatibility with USB 2.0/3.0 input specifications if used in portable devices. Ensure the thermal environment supports the specified junction temperature range.

Part Context

This part belongs to the MP2617 series of switching chargers from Monolithic Power Systems. It is specifically the B variant designed for 4.2V single-cell lithium-ion batteries, distinct from the A variant which targets 4.35V cells. The GL-Z suffix indicates the specific packaging and environmental compliance configuration for this product line.

Replacement Considerations

MP2617BGL-P is listed as a parameter-equivalent substitute by distributors.
