MP2615AGQ-P

Overview

The MP2615AGQ-P is a high-efficiency switching battery charger from Monolithic Power Systems, designed for single or dual-cell lithium-ion and lithium-polymer batteries. It operates with an input voltage range of 4.75 V to 18 V and delivers a maximum programmable charging current of 2 A. The device features a fixed output voltage of 4.2 V per cell, housed in a compact 3 mm x 3 mm QFN-16 package. It supports a maximum operating temperature of +125°C and includes internal power switches with a quiescent current of 1.1 mA.

Feature Summary

• Implements constant on-time control architecture allowing up to 99% duty cycle for efficient charging near input voltages
• Integrates dual control loops for precise constant-current and constant-voltage regulation without external compensation components
• Provides comprehensive protection mechanisms including over-temperature, cycle-by-cycle over-current, and reverse discharge lockout

Applications

• Portable electronic devices requiring single or dual-cell lithium-ion battery management
• Consumer electronics utilizing lithium-polymer battery packs
• Compact mobile hardware constrained by limited board space

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm thermal grade and packaging configuration. Ensure compatibility with system input voltage limits and battery chemistry requirements before integration. Cross-reference datasheet revisions to validate parameter consistency for production deployment.

Selection Notes

Select this component when designing systems requiring integrated power switches and high efficiency within a minimal footprint. Consider the 4.2 V per cell output specification for appropriate battery configurations. Evaluate the thermal performance characteristics relative to the expected ambient operating environment and heat dissipation constraints.
