MP2633GR-P

Overview

The MP2633GR-P is a high-integration switch-mode battery charger and power path management IC from Monolithic Power Systems. It supports single-cell Lithium-ion or Lithium Polymer batteries with an input voltage range of 4.5 V to 6 V. The device provides a programmable charging current up to 1.5 A and offers selectable output voltages of 3.6 V or 4.2 V with 0.5% accuracy. It operates in charging mode when input power is present and switches to boost mode via the MODE pin when input is removed, providing system power through the SYS pin. The QFN-24 package supports surface mount installation.

Feature Summary

• Integrated power path management that prioritizes system power requirements while managing battery charging based on input availability.
• Automatic transition to reverse boost operation mode to supply the system from the battery when the input source is disconnected.
• Comprehensive safety features including over-temperature shutdown, input over-voltage protection, and automatic recovery from output short circuits.

Applications

• Portable devices powered by single-cell lithium-ion or lithium-polymer batteries
• Systems requiring integrated battery charging and power distribution management
• Applications needing low electromagnetic interference (EMI) performance

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and electrical specifications. Ensure compatibility with the target battery chemistry and input voltage constraints before integration. Cross-reference the component marking with the datasheet to authenticate the source and prevent counterfeit risks.

Selection Notes

Select this component for designs requiring a compact solution for single-cell battery management with built-in power path control. Consider the thermal dissipation capabilities within the QFN-24 package relative to the maximum operating temperature limits. Evaluate the need for external components to set charging parameters and timer backup functions according to application requirements.
