MP2625BGL-P

Overview

The MP2625BGL-P is a fully integrated switching single-cell lithium-ion battery charger from Monolithic Power Systems, featuring Non-Volatile DC-DC (NVDC) power path management. It operates with an input voltage range of 4V to 10V and supports a programmable charging current up to 2A. The device integrates synchronous buck regulators for system output and battery charging, eliminating the need for external MOSFETs or blocking diodes. It accommodates USB and AC adapter inputs, with programmable input current limits compatible with USB 2.0 and 3.0 specifications. The IC includes comprehensive protection features such as thermal regulation and battery temperature monitoring.

Feature Summary

• Integrates NVDC power path management to ensure immediate system operation even without a battery or during deep discharge conditions.
• Features fully integrated power switches, removing the requirement for external blocking diodes and current sense resistors.
• Supports intelligent power path control that prioritizes system load requirements before directing remaining current to battery charging.
• Includes five distinct control loops: input current limit, input voltage limit, constant charge current, termination voltage, and thermal regulation.

Applications

• Single-cell lithium-ion battery charging in tablet computers
• Portable electronic devices requiring stable system voltage during charging
• USB-powered consumer electronics with strict input current constraints
• Devices utilizing large-capacity DC adapters for fast charging

Procurement Notes
