MP2639BGR-Z

Overview

The MP2639BGR-Z is a single-cell lithium-ion or lithium-polymer switching charger from Monolithic Power Systems. It supports an input voltage range of 4V to 16V and delivers up to 3A output current. The device provides a regulated 4.5V output for the battery. It operates within a temperature range of -40°C to +125°C TJ. The component is housed in a QFN-24 package with SMD/SMT installation style.

Feature Summary

• Compatible with wide input voltage ranges for flexible power source integration
• Integrated programmable OTG functionality for bidirectional power management
• Supports single-cell Li-ion and Li-polymer battery chemistries

Applications

• Portable devices requiring wide-input charging capabilities
• Systems utilizing integrated programmable OTG features
• Single-cell lithium-based battery powered electronics

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official documentation to confirm RoHS compliance status and lead time requirements. Ensure that the ordering quantity aligns with the factory packaging specifications, as indicated by distributor listings. Cross-reference the datasheet revision date to confirm the accuracy of the electrical parameters before finalizing procurement decisions.

Selection Notes

Select this model when a wide input voltage range up to 16V is required for single-cell applications. It is suitable for designs needing integrated OTG support alongside standard charging functions. Compare it against the MP2639AGR-Z variant if dual-cell support or different voltage thresholds are necessary for the target system architecture.

Part Context

This component belongs to the MP2639 series of battery management ICs from Monolithic Power Systems. The series includes variants designed for both single-cell and dual-cell configurations. The BGR-Z suffix specifically denotes the single-cell version compatible with wider input voltages compared to other family members like the AGR-Z.
