MP5077GG-Z

Overview

The MP5077GG-Z is a single-channel P-channel power switch IC from Monolithic Power Systems, designed for high-efficiency power distribution. It supports an input voltage range of 0.5V to 5.5V and delivers a continuous output current of 7A. The device features a typical on-resistance of 10 milliohms, minimizing conduction losses. Integrated protections include adjustable current limiting, over-temperature shutdown, and under-voltage lockout. It operates within a junction temperature range of -40°C to +125°C and is housed in a compact 12-QFN (2x2) surface-mount package.

Feature Summary

• Integrates controlled slew rate management to limit inrush current during load switching.
• Provides programmable current limiting with automatic retry or latching protection modes.
• Includes active load discharge functionality to rapidly de-energize floating loads upon shutdown.

Applications

• Power sequencing and distribution in portable consumer electronics
• Load switching for peripheral modules in automotive infotainment systems
• Protection circuits for USB hubs and high-current data interfaces

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pin compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and protection logic. Cross-reference datasheet revisions to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when a low-profile solution is required for high-current applications up to 7A. The 12-QFN package offers thermal efficiency for space-constrained designs. Evaluate the need for programmable current limits versus fixed thresholds based on downstream circuit requirements.

Part Context

This part belongs to the MP5077 family of high-side power switches. It shares architectural similarities with other MPS load switches but is distinguished by its specific 7A current rating and 10-milliohm on-resistance profile optimized for low-loss power routing.

Replacement Considerations

MP5077AGG-P is documented as a parameter-equivalent alternative within the same product family.
