MP5073GG-P

Overview

The MP5073GG-P is a single-channel P-channel power distribution switch IC from Monolithic Power Systems, designed for industrial applications. It operates within a supply voltage range of 3V to 5.5V and supports a maximum output current of 2A. The device features a low on-resistance of 70 mOhms (maximum) and includes programmable current limiting set at 1.4A. Additional protection mechanisms include over-temperature shutdown and under-voltage lockout. It is housed in a 12-QFN package with dimensions of 2x2 mm, suitable for surface mount installation across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates a P-channel MOSFET with high-side configuration for efficient power distribution.
• Features programmable current limit capability to protect downstream loads from overcurrent conditions.
• Includes comprehensive fault protection mechanisms such as thermal shutdown and under-voltage lockout.

Applications

• Industrial grade power distribution systems
• Load switching in embedded control circuits
• Power management for peripheral devices

Procurement Notes

Verify the specific suffix 'P' indicates the industrial grade variant when sourcing replacements or equivalents. Confirm that the 12-QFN package footprint matches the target PCB layout constraints. Ensure the programming resistor values align with the required 1.4A current limit threshold specified in the official datasheet. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component for applications requiring a compact, single-channel load switch with precise current limiting capabilities. The industrial temperature rating makes it suitable for harsh environments where standard commercial parts may fail. Consider the low on-resistance for minimizing power dissipation in high-current scenarios up to 2A. Evaluate the need for programmable limits versus fixed thresholds provided by other variants in the MPQ5073 series.

Part Context

This part belongs to the MP5073 family of power switches from Monolithic Power Systems. It is functionally similar to the MP5073GG-Z but distinguished by its industrial grade qualification. The series offers various configurations including automotive grades like the MPQ5073GG-AEC1-Z. All variants share the core architecture of a low RDS(on) P-channel switch with integrated protection features.
