MP5075LGTF-Z

Overview

The MP5075LGTF-Z is a single-channel P-channel load switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 3 V to 5.5 V and supports a continuous output current of 1 A with a maximum current limit of 1.4 A. The device features a low on-resistance (RDS(ON)) of 80 mΩ. It is housed in a compact SOT-563 surface-mount package and functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates comprehensive fault protection mechanisms including overcurrent, thermal shutdown, short-circuit, and under-voltage lockout.
• Features programmable slew rate control to minimize inrush current during power-up sequences.
• Includes an integrated output discharge function to rapidly pull down the load when the switch is disabled.

Applications

• Power distribution networks in portable consumer electronics
• Load switching for peripheral devices in industrial equipment
• Voltage regulation stages in automotive infotainment systems

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status as per manufacturer declarations. Confirm the SOT-563 package variant matches the footprint requirements of the target PCB design. Ensure the input voltage does not exceed the 5.5 V absolute maximum rating to prevent device damage.

Selection Notes

Select this component for applications requiring precise inrush current management via slew rate control. The 80 mΩ on-resistance offers a balance between conduction loss and cost for 1 A loads. Consider the SOT-563 package size constraints relative to available board space and thermal dissipation needs.

Part Context

This part belongs to the MP5075 series of high-side load switches designed for efficient power distribution. It serves as a protective interface between power sources and sensitive downstream loads, replacing discrete MOSFET solutions to reduce component count and improve reliability in space-constrained designs.

Replacement Considerations

The MP5075LGTF-P is a compatible alternative within the same series offering identical electrical specifications and pinout compatibility in the SOT-563 package.

FAQ

How does the MP5075LGTF-Z manage inrush current?

It utilizes a programmable slew rate control feature that gradually turns on the internal P-channel MOSFET, limiting the initial surge of current into capacitive loads.

What happens to the load voltage when the switch is turned off?

The device activates an internal output discharge path that actively pulls the load voltage to ground, ensuring rapid discharge of stored energy.
