MP2623GR-P

Overview

The MP2623GR-P is a monolithic DC-DC buck switching charger designed for 1 to 2 series-connected Lithium Iron Phosphate (LiFePO4) batteries. It integrates an upper power MOSFET capable of delivering up to 2A of charging current. The device operates with an input voltage range of 5V to 24V and provides a fixed output voltage of 3.3V. It utilizes current control mode for fast loop response and employs two control loops to precisely regulate charging current and voltage. Key electrical parameters include a battery voltage accuracy of 0.75%, a fixed switching frequency of 1.1MHz, and a maximum power dissipation of 2.7W. The component functions within a temperature range of -40°C to +125°C and features a QFN-16 package.

Feature Summary

• Integrates an internal power MOSFET to minimize external component count
• Supports trickle charging for depleted battery cells
• Includes battery temperature monitoring and protection mechanisms
• Provides charging status and input fault indication

Applications

• Charging single-cell LiFePO4 battery packs
• Charging two-series LiFePO4 battery configurations
• Portable electronic devices requiring LiFePO4 power sources

Procurement Notes

Verify the specific suffix 'P' against official Monolithic Power Systems documentation to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with the required QFN-16 footprint and thermal management requirements during integration. Cross-reference the part number with the manufacturer's latest datasheet to validate RoHS compliance status and environmental certifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems specifically utilizing LiFePO4 chemistry rather than standard Lithium-ion cells. The fixed 3.3V output makes it suitable for applications where the battery pack voltage aligns with this regulation level. Consider the 1.1MHz switching frequency for balancing EMI performance and passive component size. Verify that the system input voltage remains within the 5V to 24V operational window to ensure stable charging performance.

Part Context

This part belongs to the MP2623 family of switching chargers from Monolithic Power Systems. It is categorized under Battery Management ICs within the PMIC segment. The device is distinct from other MPS chargers by its specific optimization for LiFePO4 chemistry and its integrated high-side switch topology. It shares the QFN-16 package form factor with other components in the broader MPS portfolio but differs in chemical compatibility and control architecture.
