MP6219DN-LF

Overview

The MP6219DN-LF-Z is a power distribution switch IC from Monolithic Power Systems, designed for high-side load switching applications. It features a single output channel with a continuous output current of 500 mA and a programmable current limit set to 2 A. The device operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum on-resistance of 82 mOhms. It supports active-high control logic and includes protection against over-temperature conditions. The component is housed in an SOIC-8E surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates a high-side power switch with programmable current limiting capability for precise load protection.
• Features low on-resistance to minimize conduction losses and power dissipation during normal operation.
• Includes thermal shutdown protection to safeguard the device and connected loads under fault conditions.

Applications

• Power distribution systems requiring individual channel current limiting
• High-side switching for peripheral devices in embedded systems
• Load protection circuits in industrial control modules

Procurement Notes

Verify the specific suffix (LF-Z) to confirm the tape-and-reel packaging format and lead-free compliance status. Confirm that the 4.5 V minimum operating voltage aligns with your system's power rail, as this part does not support lower voltage inputs. Check for moisture sensitivity labeling if storage conditions exceed specified limits.

Selection Notes

Select this component when a fixed 2 A current limit is acceptable for the target load, as the limit is programmable but typically set by external resistors or internal defaults depending on the exact variant configuration. Ensure the input voltage stays above 4.5 V. Consider the SOIC-8E package size for PCB layout constraints compared to smaller alternatives like MSOP.

Part Context

This part belongs to the MP6219 series of power distribution switches from MPS. It is distinct from other series like the MP62181 which may offer different current ratings or input voltage ranges. The MP6219 series focuses on providing robust protection features in a compact footprint suitable for dense electronic designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any legacy replacements by matching the 500 mA output current, 2 A limit, and 4.5-5.5 V input range specifications.
