MP6219DN-LF-Z

Overview

The MP6219DN-LF-Z is a programmable current limit power switch IC manufactured by Monolithic Power Systems. It supports an input voltage range of 2.7 V to 5.5 V and delivers a continuous output current of 2 A. The device features a maximum on-resistance of 120 mΩ and includes a programmable current limit set at 2.8 A. It incorporates timing controls with a maximum run time of 10 ms and a maximum idle time of 3 ms. The component operates within a temperature range of -40°C to +85°C and is housed in an SOIC-EP-8 package.

Feature Summary

• Integrates programmable current limiting for precise load protection
• Features low on-resistance for efficient power distribution
• Includes configurable run and idle timing for controlled switching

Applications

• Power distribution systems requiring programmable load management
• Peripheral power switching in industrial control units
• Protection circuits for sensitive electronic loads

Procurement Notes

Verify the specific suffix and package variant against official datasheets before procurement, as designator changes may affect electrical characteristics or pinout compatibility. Confirm end-of-life status with the manufacturer, as this component is marked as Not Recommended for New Designs (NRND). Ensure supply chain sources provide authentic parts with valid traceability documentation to mitigate counterfeit risks.

Selection Notes

Select this component when a fixed current limit is insufficient for the application requirements. The programmable nature allows customization of protection thresholds via external components. Verify that the required input voltage falls within the 2.7 V to 5.5 V operational window. Consider the thermal performance of the SOIC-EP-8 package under maximum load conditions to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the MPS power switch IC family designed for power distribution applications. It serves as a protective element between the power source and the load, offering overcurrent protection and controlled turn-on/turn-off sequences. The series typically integrates high-side switching capabilities with diagnostic features suitable for robust system architectures.
