MP2617HGL-Z

Overview

The MP2617HGL-Z is a single-cell lithium-ion switching charger from Monolithic Power Systems, designed for wide input voltage applications. It operates within a supply voltage range of 4 V to 14 V and delivers a maximum output current of 3 A. The device features a fixed output voltage of 4.2 V and utilizes a QFN-20 package for surface mount installation. It supports an operating temperature range from -40 °C to +125 °C with a power dissipation rating of 2.6 W.

Feature Summary

• Integrates NVDC power path management to prioritize system load while charging the battery
• 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 portable devices
• Power management for tablets and handheld electronics
• Systems requiring simultaneous operation and battery charging via NVDC path

Procurement Notes

Verify the specific suffix Z against official MPS documentation to confirm lead time and packaging details. Ensure the 14V input capability matches your system design requirements. Confirm RoHS compliance status through the manufacturer's environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a wider input voltage range up to 14 V is required compared to standard 10 V variants. The integrated synchronous buck regulator eliminates external diodes. Verify that the QFN-20 footprint fits the PCB layout constraints and that the thermal performance meets the application's heat dissipation needs.

Part Context

This part belongs to the MP2617 series of switching chargers. It shares functional similarities with models like MP2617AGL-Z and MP2617BGL-Z but differs primarily in its extended input voltage specification. The H-series variant specifically targets applications requiring higher input voltage tolerance.

Replacement Considerations

MP2617HGL-P is a pin-compatible alternative within the same series.
