Overview
The MP2637AGR-P is a single-cell switch-mode battery charger from Monolithic Power Systems, designed for lithium-ion and lithium-polymer batteries. It features an integrated power-path management system that prioritizes system power while charging the battery. The device supports a maximum charge current of 2.5A and provides up to 2.4A of boost current for system operation when input power is disconnected. It operates within a 4.5V to 6V input voltage range and offers a fixed 4.2V output voltage with 0.5% accuracy. The component is housed in a QFN-24 package and functions across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates power-path management to balance system load and battery charging simultaneously
- Supports reverse boost mode to supply system power from the battery when input is absent
- Includes comprehensive safety protections such as over-temperature shutdown and short-circuit protection
Applications
- Portable consumer electronics powered by single-cell lithium batteries
- Smartphones and mobile communication devices requiring efficient power path management
- Wearable technology with strict space and thermal constraints
- IoT devices utilizing Li-ion or Li-Polymer energy storage
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with standard SMD/SMT assembly processes for QFN-24 packages. Cross-reference the part number with the latest datasheet revision to confirm pinout integrity and electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component for applications requiring high-efficiency charging with simultaneous system power delivery. The integrated power-path management eliminates the need for external switching components for system load sharing. Consider the 2.5A charge capability and 2.4A boost output when sizing the power budget for portable systems. Verify that the input source can support the required current without triggering input current limits.
Part Context
The MP2637 belongs to the MP2637A series of battery chargers from Monolithic Power Systems. It is part of a family of highly integrated PMIC solutions designed for portable electronics. The AGR variant typically denotes specific packaging and environmental compliance attributes within the MPS portfolio, distinguishing it from other suffixes like GR-Z which may differ in reel configuration or regional compliance standards.
Replacement Considerations
Direct substitutes include the MP2637GR-Z and MP2637GR-P. These variants share identical electrical specifications and pinouts but may differ in packaging format or regional certification. Verify that any replacement maintains the same QFN-24 footprint and thermal performance requirements.
