MP2635AGR-Z

Overview

The MP2635AGR-Z is a single-cell switching battery charger from Monolithic Power Systems designed for lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 4.5 V to 6 V and delivers a maximum output charging current of 2 A. The device supports adjustable output voltages between 2.5 V and 4.35 V. It features integrated power path management and a 1 A BOOST OTG capability. The component is housed in a QFN-24 package, suitable for surface mount installation, with an operating temperature range spanning from -20 °C to +85 °C.

Feature Summary

• Integrates system power path management to prioritize system loads while charging the battery
• Supports reverse boost operation for on-the-go power delivery when input power is absent
• Includes comprehensive safety protections such as over-temperature shutdown and short-circuit protection

Applications

• Portable devices powered by single-cell lithium-ion or lithium-polymer batteries
• Power bank applications requiring OTG functionality
• Systems needing integrated charge management and power path control

Procurement Notes

Verify the specific suffix 'Z' against official datasheets to confirm environmental compliance status and lead time requirements. Confirm that the QFN-24 package dimensions match your PCB footprint design. Ensure input supply constraints align with the specified 4.5 V to 6 V operational range for proper functionality.

Selection Notes

Select this component for designs requiring a compact solution for single-cell Li-ion or Li-Po batteries. It is suitable where power path management and boost output are necessary. Compare thermal performance and efficiency requirements against the 2 A current limit. Verify compatibility with the required charging voltage settings within the 2.5 V to 4.35 V range.

Part Context

This part belongs to the MP2635A series of highly integrated switch-mode battery chargers. It shares functional similarities with other variants like the MP2635GR-P but differs in packaging and environmental specifications. The series is designed for portable electronics, offering flexibility in charging profiles and system power management through configurable pins.

Replacement Considerations

MP2635GR-P is listed as a parameter-equivalent alternative. Verify pinout compatibility and environmental rating differences before substitution.
