MP2759AGQ-0000-Z

Overview

The MP2759AGQ-0000-Z is a battery management IC from Monolithic Power Systems designed for 1 to 6-cell Lithium-ion and Lithium Polymer batteries. It operates as a 36V switching charger with integrated power path management. Key electrical parameters include a maximum input voltage of 36V, a maximum charge current of 3A, and an output voltage range up to 5V. The device supports a maximum output current of 30mA for system loads. It functions within a temperature range of -40°C to +125°C TJ and is housed in a 19-QFN (3x3) package.

Feature Summary

• Integrates narrow NTC window support for precise thermal monitoring
• Includes built-in power path management for seamless load transfer
• Supports multi-cell battery configurations up to six cells

Applications

• Charging systems for 1-6 cell Lithium-ion battery packs
• Charging systems for 1-6 cell Lithium Polymer battery packs
• Portable electronic devices requiring high-voltage input charging

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout and functional variations. Confirm RoHS compliance status through the manufacturer's environmental declaration. Ensure the QFN-19 footprint matches the target PCB layout. Validate that the narrow NTC window requirement aligns with the selected thermistor characteristics for the intended application design.

Selection Notes

Select this component when designing chargers for multi-cell battery stacks requiring up to 36V input. It is suitable for applications needing integrated power path management to handle system loads during charging. Consider the 19-QFN package size for space-constrained designs. Verify compatibility with the required NTC thermistor resistance values due to the narrow window specification.

Part Context

This part belongs to the MP2759A series of battery charge management ICs by Monolithic Power Systems. It is categorized under PMIC - Battery Chargers. The device is distinct from single-cell chargers like the MP2635AGR-Z or general buck converters like the MP2303. It specifically targets higher voltage multi-cell battery applications compared to standard single-cell solutions.

Replacement Considerations

MP2759AGQ-0000-P is listed as a related variant with identical core functionality but different packaging options.
