MP2625BGL-Z

Overview

The MP2625BGL-Z is a single-cell lithium-ion switch-mode battery charger featuring NVDC power path management. It integrates a synchronous buck regulator to supply system output while charging the battery. The device supports an operating input voltage range of 4V to 10V and delivers a maximum charge current of 2A with a programmable terminal voltage of 4.2V. It operates at a switching frequency of 1.6MHz and includes five control loops: input current limit, input voltage limit, constant charge current, terminal voltage control, and thermal fold-back. The component is housed in a 20-QFN (3x4) package.

Feature Summary

• Integrates smart power path management for simultaneous system powering and independent battery charging
• Supports USB 2.0/3.0 and AC adapter inputs with programmable input current limits
• Includes built-in thermal limiting regulation and battery temperature monitoring
• Fully integrated power switches eliminate need for external blocking diodes or sense resistors

Applications

• Single-cell Li-ion battery charging in tablet computers
• Portable electronic devices requiring NVDC power path management
• USB-powered portable equipment
• Devices utilizing high-power DC adapters

Procurement Notes

Verify that the specific suffix GL-Z corresponds to the required tape-and-reel packaging configuration as defined by Monolithic Power Systems. Confirm compatibility with the 20-QFN footprint during PCB layout. Ensure design requirements align with the 4V to 10V input range and 2A maximum charge current specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-cell Li-ion solution requires integrated power path management to prioritize system load over battery charging. It is suitable for designs needing support for both USB and DC adapter inputs with programmable current limits. Consider the 1.6MHz switching frequency for EMI performance and the compact QFN package for space-constrained applications.

Part Context

This part belongs to the MP2625 series of switch-mode chargers from Monolithic Power Systems. While the base MP2625 model is not recommended for new designs, the MP2625B variant remains in production. This specific IC serves as the designated alternative for new designs within the family, offering enhanced features compared to legacy models.

Replacement Considerations

For new designs replacing the discontinued MP2625, use MP2625BGL-Z. Existing customers using MP2625 may continue production runs but should transition to this B-series variant.
