MP2659GQ-0000-Z

Overview

The MP2659GQ-0000-Z is a standalone switching charger designed for multi-cell series battery packs, supporting lithium-ion and lithium-polymer chemistries. It integrates internal power MOSFETs to minimize external component count. The device operates on an input voltage range of 4V to 36V and delivers a maximum charging current of 3A. It supports battery configurations from three to six cells in series. Key electrical parameters include a maximum power dissipation of 2.5W and a quiescent supply current of 550µA. The unit functions within a temperature range of -10°C to +125°C TJ.

Feature Summary

• Integrates high-efficiency synchronous rectification with internal power MOSFETs for compact design.
• Provides programmable constant current and constant voltage charging profiles.
• Includes comprehensive protection mechanisms against over-temperature and over-voltage conditions.

Applications

• Portable electronic devices requiring multi-cell battery management
• Industrial equipment utilizing series-connected lithium batteries
• Medical devices demanding reliable standalone charging solutions

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required packaging formats. Confirm that the operating environment remains within the specified thermal limits. Check for updated revision levels to match existing bill of materials. Ensure input voltage sources do not exceed the absolute maximum ratings during transient events.

Selection Notes

Select this component when designing systems with three to six series-connected lithium cells. Choose this part if integrated MOSFETs are preferred to reduce board space. Consider this IC for applications requiring wide input voltage ranges up to 36V. Evaluate thermal performance carefully due to the 2.5W power dissipation limit.

Part Context

This model belongs to the MP2658/MP2659 family of battery chargers from Monolithic Power Systems. It shares architectural similarities with the MP2658 but offers higher current capabilities. The QFN-19 package is standard for this series, facilitating surface-mount assembly. It complements other PMIC offerings in portable power management portfolios.

Replacement Considerations

The MP2659GQ-0000-P is listed as a direct substitute by the manufacturer. Verify pinout and functional equivalence before swapping. Ensure that any alternative components meet the same thermal and electrical specifications.
