MP2636GR-Z

Overview

The MP2636GR-Z is a single-cell switching charger from Monolithic Power Systems designed for lithium-ion and lithium-polymer batteries. It operates within a 4.5 V to 6 V input voltage range and supports up to 3 A programmable charging current. The device integrates power-path management, allowing simultaneous battery charging and system power supply. It features a reverse boost mode capable of delivering up to 3 A system output current when no input source is present. Packaged in a QFN-30 (4x4 mm) format, it functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates power-path management to prioritize system power while charging the battery
• Supports reverse boost operation to supply system load directly from the battery
• Includes comprehensive fault protection mechanisms such as over-temperature and short-circuit protection

Applications

• Portable electronic devices powered by single-cell lithium-ion or lithium-polymer batteries
• Systems requiring simultaneous battery charging and system power distribution
• Applications necessitating backup power delivery via reverse boost mode

Procurement Notes

Verify the specific suffix Z against official MPS documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and input voltage constraints. Cross-reference the QFN-30 footprint dimensions with your PCB layout guidelines. Confirm that the selected variant meets all necessary regulatory compliance standards for your target market before finalizing procurement.

Selection Notes

Select this component when designing systems that require integrated power-path management for single-cell lithium batteries. It is suitable for applications needing high-efficiency switching charging with up to 3 A capability. Consider the reverse boost feature if the design requires powering the system directly from the battery during input loss. Ensure the thermal design accommodates the specified junction temperature limits and power dissipation requirements.

Part Context

The MP2636GR-Z belongs to the MP2636 series of battery charge management ICs manufactured by Monolithic Power Systems. This series focuses on providing efficient power solutions for portable electronics. The GR-Z suffix typically denotes a specific packaging configuration, often associated with tape-and-reel delivery for automated assembly processes within the broader MP2636 product family.

Replacement Considerations

MP2636GR-P is a documented alternative within the same series offering similar functionality with potential packaging differences.
