MP2615GQ-Z

Battery Chargers Overview

The MP2615GQ-Z is a high-efficiency switch-mode battery charger designed for single or dual-cell lithium-ion and lithium-polymer batteries. It supports an input voltage range of 4.75 V to 18 V and delivers a programmable maximum charging current of 2 A, regulated via an external sense resistor. The device provides a fixed output voltage of 4.2 V with ±0.75% accuracy. Operating within a temperature range of -40°C to +125°C, it utilizes a QFN-16 (3mm x 3mm) surface-mount package.

Battery Chargers Feature Summary

• Implements constant-off-time control mode enabling up to 99% duty cycle operation for sustained high charge currents near input voltages
• Integrates full power switches and internal loop compensation while eliminating the need for external reverse blocking diodes
• Monitors battery temperature and charging status continuously with dedicated indicator pins for system feedback

Battery Chargers Applications

• Single-cell lithium-ion battery charging systems
• Dual-cell lithium-ion battery charging applications
• Lithium-polymer battery management circuits
• Portable electronic devices requiring efficient USB or adapter charging

Battery Chargers Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number MP2615GQ-Z with official Monolithic Power Systems documentation. Confirm that the specific suffix Z aligns with RoHS compliance requirements as indicated in public datasheets. Ensure the QFN-16 package dimensions match your PCB footprint specifications before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when designing systems requiring high efficiency across wide input voltage ranges from 4.75 V to 18 V. It is suitable for applications needing precise voltage regulation with ±0.75% accuracy and integrated thermal protection. Consider the 3mm x 3mm QFN-16 package constraints for space-limited designs requiring surface-mount installation.

Battery Chargers Part Context

This device belongs to the MP2615 series of battery chargers manufactured by Monolithic Power Systems. It is categorized under PMIC battery management solutions. The GQ-Z suffix denotes the specific package type and environmental compliance status within the product lineup, distinguishing it from other variants like the MP2615GQ-P.

Battery Chargers Replacement Considerations
