MP26029GQ-0000-P

Overview

The MP26029GQ-0000-P is a standalone linear lithium-ion battery charger manufactured by Monolithic Power Systems. It supports an output current of 1A and operates with a supply voltage range of 4.5V to 6V. The device features thermal regulation to manage heat dissipation during charging. It is housed in a QFN package suitable for surface mount technology applications.

Feature Summary

• Integrates thermal regulation to automatically adjust charging current based on junction temperature
• Supports standard constant-current and constant-voltage charging profiles for lithium-ion cells
• Includes status indicators for charge completion and input power presence

Applications

• Portable consumer electronics requiring single-cell lithium-ion power sources
• Battery-powered IoT devices with limited board space
• USB-powered accessory charging circuits

Procurement Notes

Verify the suffix designation carefully, as the -P variant may differ from the -Z reel configuration regarding packaging or specific manufacturing lot attributes. Confirm RoHS compliance status through official documentation before integration. Ensure the selected package matches the PCB footprint design specifications exactly to avoid assembly errors.

Selection Notes

Select this component when a simple, low-component-count linear solution is preferred over switching architectures. It is suitable for applications where input voltage is close to the battery voltage, minimizing power loss. Consider the thermal performance requirements of the final enclosure, as linear chargers dissipate excess energy as heat during high-current charging phases.
