MP2615BGQ-P

Overview

The MP2615BGQ-P is a high-efficiency switching battery charger from Monolithic Power Systems, designed for single-cell lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 4.75V to 18V and delivers a maximum charging current of 2A, adjustable via an external resistor. The device utilizes constant on-time control to maintain high duty cycles, ensuring efficient charging even when battery voltage approaches the input level. Key electrical parameters include a full-charge voltage accuracy of ±0.75%, with selectable options of 4.1V or 4.2V per cell. Integrated power switches eliminate the need for external blocking diodes, while features such as pre-charging, thermal regulation, and cycle-by-cycle overcurrent protection ensure robust operation.

Feature Summary

• High-efficiency switching architecture with integrated power switches
• Constant on-time control mode for optimal performance across input ranges
• Dual control loops for precise constant-current and constant-voltage regulation
• Comprehensive protection suite including thermal monitoring and reverse discharge lock

Applications

• Single-cell lithium-ion battery charging systems
• Lithium-polymer battery management in portable electronics
• Consumer devices requiring compact power management solutions
• Industrial equipment utilizing 1S Li-ion power sources

Procurement Notes

Verify that the specific suffix 'P' corresponds to the required tape-and-reel packaging configuration rather than cut-tape samples. Confirm that the BGQ variant aligns with the intended operating temperature range and regulatory compliance requirements for the target application. Cross-reference the exact part number against the manufacturer's latest datasheet revision to ensure all electrical specifications and pinout definitions remain consistent with the design implementation.

Selection Notes

Select this component for applications requiring a compact footprint due to its 3mm x 3mm QFN-16 package. It is suitable for designs needing up to 2A charging current with wide input voltage tolerance. Consider the internal loop compensation and lack of external diode requirement to simplify the bill of materials. Ensure the system can accommodate the programmable charge timer and temperature monitoring interfaces provided by the IC.
