MP2760GVT-0000-Z

Overview

The MP2760GVT-0000-Z is an I2C-controlled buck-boost battery charger designed for 1-cell to 4-cell series battery packs. It supports a wide input voltage range of 4V to 22V, accommodating battery voltages higher or lower than the input. The device integrates narrow voltage direct current (NVDC) power path management with an external N-channel MOSFET driver. It features four-stage charging: trickle, pre-charge, constant current, and constant voltage, with automatic recharge capability. Input current and voltage limits prevent source overload, ensuring compatibility with USB and USB Power Delivery specifications.

Feature Summary

• Buck-boost topology enables smooth switching between step-down and step-up modes regardless of battery voltage relative to input.
• Integrated NVDC power path management regulates system minimum voltage and provides battery backup functionality via external MOSFET control.
• I2C/SMBus interface allows configurable charge parameters, including input current limits, charging current, and full-charge adjustment voltage.
• Comprehensive safety features include input overvoltage protection, system overvoltage protection, battery overvoltage protection, and thermal shutdown.

Applications

• Portable consumer electronics requiring robust battery charging
• USB-powered devices compatible with USB PD 3.0 specifications
• Applications utilizing 1 to 4 series Li-ion or Li-polymer battery cells
• Systems requiring integrated power path management for seamless operation

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component matches the required cell count configuration for your specific battery architecture. Cross-reference the part number with authorized distributors to confirm current availability status and lead times, as supply chain conditions may vary. Confirm that the selected variant aligns with your design-in requirements for interface protocols and thermal performance.

Selection Notes

Select this component when designing systems with 1 to 4 series battery cells requiring flexible input voltage ranges from 4V to 22V. It is suitable for applications needing integrated power path management to maintain system uptime during battery depletion. Choose this IC for designs requiring I2C configurability for precise charge termination and input current limiting. Ensure the application environment supports the TQFN-30 package and operates within the specified temperature range for optimal reliability.

Part Context

The MP2760 belongs to Monolithic Power Systems' family of advanced battery management solutions. It is specifically engineered for multi-cell series configurations, distinguishing it from single-cell chargers. The device addresses the need for high-efficiency charging in space-constrained portable devices by integrating power path management directly into the charger controller. This integration reduces component count and simplifies board layout compared to discrete solutions.

Replacement Considerations

Direct replacements should be sought within the MPS MP2760 series or compatible buck-boost chargers supporting similar cell counts. Verify pin-to-pin compatibility if substituting in existing layouts. Consider alternatives only if they support the same NVDC power path management and I2C configurability requirements. Ensure any substitute maintains compatibility with USB PD standards if applicable to the original design intent.

FAQ

Does the MP2760 support both charging and discharging modes?

Yes, the MP2760 supports charging mode when an input source is present and can operate in a source mode to provide output voltage through the IN pin, subject to configuration.

What is the maximum number of battery cells supported?

The MP2760 is designed to support battery packs consisting of 1 to 4 series-connected cells.

How does the device manage system power when the battery is low?

It utilizes integrated NVDC power path management to regulate the system minimum voltage, allowing the system to run directly from the input source while charging the battery or supplementing it if necessary.
