MP2681BGS-P

Overview

The MP2681BGS-P is a monolithic lithium-ion or lithium-polymer battery charging controller designed for power tool applications. It integrates constant current and constant voltage regulation with full protection features in a single chip. The device supports AC adapter inputs and desk-style chargers, operating within a supply voltage range of 4.5 V to 30 V. It utilizes a 16-pin SOIC package and functions at temperatures from -40°C to +125°C. Key electrical parameters include a maximum power dissipation of 1.6 W and a quiescent current of 490 µA.

Feature Summary

Automatic battery cell detection via ID resistor to adjust charging voltage for various configurations
Integrated three-stage charging process including pre-charge, constant current, and constant voltage phases
Comprehensive safety mechanisms including NTC temperature monitoring, charge timeout, and fault control

Applications

Power tool battery chargers
AC adapter input charging systems
Desk-style battery charger designs

Procurement Notes

Verify the specific suffix against official Monolithic Power Systems documentation to confirm pinout compatibility and functional variations. Ensure the selected variant matches the required thermal performance and packaging specifications for the target application environment. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component for applications requiring integrated cell detection and multi-cell configuration support. Evaluate the thermal requirements given the 1.6 W power dissipation limit in the SOIC-16 package. Confirm that the input voltage range aligns with the available AC adapter outputs and that the system design accommodates the necessary external components for NTC monitoring and timer settings.
