MP2651GVT-040A-P

Overview

The MP2651GVT-040A-P is an I2C-controlled buck-boost battery charger designed for 1 to 4-series lithium-ion or lithium-polymer battery packs. It features a reverse source mode, allowing the device to act as a power source when the input voltage drops below the battery voltage. The IC integrates NVDC (Non-Volatile Deep Discharge) power path management to ensure system stability during low-input conditions. It supports USB OTG functionality and operates within a wide input voltage range of 4V to 21V. The component is housed in a 30-pin TQFN package measuring 4mm by 5mm.

Feature Summary

• I2C-controlled buck-boost charging architecture supporting 1S to 4S battery configurations
• Reverse source mode capability for power delivery when input is unavailable
• Integrated NVDC power path management for seamless system operation
• USB On-The-Go (OTG) support for host-mode connectivity

Applications

• Portable consumer electronics requiring robust power path management
• Battery-powered devices with variable input sources
• Applications necessitating USB OTG host functionality
• Systems utilizing 1S to 4S lithium-based battery packs

Procurement Notes

Verify the specific suffix '040A-P' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Ensure compatibility with the 30-TQFN (4x5) package dimensions for PCB layout. Cross-reference the I2C address configuration options provided in the technical documentation to avoid bus conflicts in multi-device systems.

Selection Notes

Select this component when a buck-boost topology is required to handle input voltages both above and below the battery pack voltage. The integrated reverse source mode makes it suitable for applications where the device must supply power to peripherals during input loss. Consider the I2C interface for precise control and monitoring capabilities compared to fixed-function chargers.

Part Context

This part belongs to the MPS MP2651 series of battery management ICs. It is functionally related to the MP2761GVT-0400-P and MP2650GV-0000-Z but offers distinct reverse source capabilities. The MP2651 series targets high-performance portable applications requiring flexible power routing and comprehensive battery protection features.
