MP2731GQC-0000-Z

Overview

The MP2731GQC-0000-Z is a single-cell fast charger from Monolithic Power Systems designed for lithium-ion and lithium-polymer batteries. It features an integrated NVDC power path, USB OTG support, and an integrated ADC. The device operates on a supply voltage of 3.7 V to 16 V and delivers an output current of 4.5 A. It is housed in a QFN-26 package (26-PowerVFQFN, 3.5x3.5 mm) suitable for surface mount installation. The component supports an operating temperature range from -40°C to +125°C with a maximum power dissipation of 2.6 W.

Feature Summary

• Integrates Non-Volatile Data Cell (NVDC) power path management for seamless source switching between adapter and battery.
• Supports USB On-The-Go (OTG) functionality to enable the device to act as a USB host.
• Includes an integrated Analog-to-Digital Converter (ADC) for enhanced system monitoring capabilities.

Applications

• Smartphones
• Portable audio and video devices
• Personal Digital Assistants (PDAs)

Procurement Notes

Verify availability status carefully, as this specific part number may be subject to limited supply or discontinuation by the manufacturer. Confirm that the QFN-26 package dimensions align with your PCB footprint design. Ensure your bill of materials accounts for potential lead time variations due to restricted distribution channels.

Selection Notes

Select this component when a high-current single-cell charging solution with integrated power path management is required. The inclusion of OTG and ADC features makes it suitable for complex portable systems. Verify compatibility with the target lithium-ion or lithium-polymer battery chemistry before finalizing the design.

Part Context

This part belongs to the MP2731 series of battery charge management ICs from Monolithic Power Systems. It is functionally similar to the MP2731GQC-0000-P variant, though packaging or revision differences may exist. It serves as a specialized PMIC for portable electronics requiring efficient single-cell charging and power routing.

Replacement Considerations

The MP2731GQC-0000-P is a documented alternative within the same product family. Verify pinout compatibility and functional equivalence before substitution. No other public substitute part numbers are confirmed for direct replacement.
