MP2617HGL-P

Overview

The MP2617HGL-P is a single-cell lithium-ion battery switching charger from Monolithic Power Systems, designed for wide input voltage applications. It supports an operating supply voltage range of 4 V to 14 V and delivers a maximum output charging current of 3 A. The device features a fixed output voltage of 4.2 V, suitable for standard Li-ion cells. It operates within a junction temperature range of -40 °C to +125 °C and dissipates up to 2.6 W of power. The component is housed in a QFN-20 package (3x4 mm) and draws a typical operating supply current of 40 mA.

Feature Summary

• Integrates NVDC smart power path management to prioritize system load while charging the battery
• Supports both USB and high-power DC adapter inputs with adjustable input current limiting
• Includes five control loops: input current limit, input voltage limit, constant charge current, battery cutoff, and thermal foldback
• Features integrated synchronous buck regulator and full power switches without external blocking diodes

Applications

• Single-cell lithium-ion battery charging for tablets
• Portable electronic devices requiring NVDC power path management
• Systems powered by USB or DC adapters with variable input voltages

Procurement Notes

Verify the specific suffix 'P' indicates cut tape packaging versus 'Z' for reel packaging when ordering. Confirm the 14V input rating aligns with your source design, as other variants support lower voltages. Ensure the QFN-20 footprint matches your PCB layout. Check RoHS compliance status via official datasheets before finalizing procurement specifications.

Selection Notes

Select this model specifically for applications requiring a 14V maximum input voltage, distinguishing it from the 10V variants like the MP2617BGL. Consider the 3A current capability for faster charging cycles. Evaluate the QFN-20 package size against available board space. Verify that the 4.2V output voltage matches the target battery chemistry requirements.

Part Context

This component belongs to the MP2617 series of PMICs from Monolithic Power Systems. The series includes variants such as MP2617A and MP2617B, which differ primarily in their maximum supported input voltage ranges. The H-series designation typically denotes the wider input voltage capability compared to the B-series.

Replacement Considerations

MP2617HGL-Z is a parameter-equivalent alternative differing only in packaging format.
