MP5087AGG-P

Overview

The MP5087AGG-P is a single-channel P-channel power switch IC from Monolithic Power Systems, designed for load distribution applications. It supports an input voltage range of 0.5V to 5.5V and delivers a maximum output current of 7A with a typical on-resistance of 10 milliohms. The device features adjustable current limiting at 1.64A, along with over-temperature protection and under-voltage lockout. Operating within a temperature range of -40°C to +125°C, it is housed in a compact 12-QFN (2x2 mm) surface-mount package.

Feature Summary

• Integrates adjustable current limiting and thermal shutdown for robust fault protection
• Features low on-resistance to minimize conduction losses in power distribution paths
• Includes slew rate control to manage inrush current during turn-on events

Applications

• Peripheral power switching in portable electronic devices
• Load distribution in industrial control systems
• Power management in automotive infotainment units

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging when ordering. Confirm that the 12-QFN footprint matches your PCB layout requirements. Ensure voltage ratings align with your system's maximum supply levels. Check RoHS compliance status if required by your manufacturing standards. Validate lead times directly with authorized distributors as availability may vary.

Selection Notes

Select this component for high-current single-channel applications requiring precise load control. Compare against the MP5086 series if NTC comparator functionality is needed instead of standard switching. Consider the MP5090 series for dual-channel requirements. Evaluate thermal performance based on ambient conditions and board copper area. Verify compatibility with system logic levels for the enable interface.

Part Context

This part belongs to the MP5087 family of power switches, which are optimized for efficiency and compact design. The AGG variant specifies the QFN-12 package and tape-and-reel delivery format. It serves as a direct replacement for legacy discrete MOSFET solutions in space-constrained designs. The family shares common pinouts with related models for easier migration.

FAQ

What is the function of the slew rate control feature?

Slew rate control limits the rate of voltage rise at the output, reducing inrush current and preventing voltage droop on the input supply line during startup.

How is the current limit threshold determined?

The current limit is adjustable via an external resistor connected to the ILIM pin, allowing customization of the protection threshold up to the device's maximum rating.
