MP26029GTF-0000-P

Overview

The MP26029GTF-0000-P is a standalone linear Li-Ion battery charger from Monolithic Power Systems. It supports a programmable charging current of up to 1A and operates within an input voltage range of 4.35V to 5.5V. The device features thermal regulation for safe operation and includes a trickle charge function for deeply discharged batteries. It is housed in a GTF package and is designed for single-cell Lithium-ion or Lithium-polymer batteries.

Feature Summary

• Integrates thermal regulation to manage junction temperature during high-current charging
• Supports programmable constant current and constant voltage charging profiles
• Includes automatic recharge functionality triggered by voltage drop below threshold

Applications

• Portable consumer electronics requiring compact power management
• Single-cell lithium-ion battery powered devices
• Lithium-polymer battery charging systems

Procurement Notes

Verify the specific suffix 'GTF' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad requirements. Ensure the ordering code matches the exact package variant required for your PCB layout. Cross-reference the full part number with MPS documentation to avoid confusion with similar series components that may have different electrical characteristics or pin configurations.

Selection Notes

Select this component when a simple, low-component-count solution for single-cell Li-Ion/Polymer charging is needed. It is suitable for applications where input voltage stability between 4.35V and 5.5V can be maintained. Consider the thermal performance of the GTF package relative to the expected ambient conditions and maximum charging current requirements of the target design.

Part Context

This part belongs to the MP26029 series of standalone linear chargers. It is distinct from switching regulators like the MP2269 or boost converters like the MP28600 found in related listings. The series focuses on linear topology for simplicity and noise reduction in battery charging applications.

Replacement Considerations

MP26029GN-0000-Z is listed as a direct substitute.
