MP5007DQ-LF-P

Overview

The MP5007DQ-LF-P is a programmable current limit switch designed for power distribution applications. It operates within an input voltage range of 4 V to 6 V and supports up to 5 A output current with a typical current limit of 2.1 A. The device integrates a low on-resistance power MOSFET, achieving a maximum Rds(on) of 43 mΩ. It features adjustable output voltage slope and current limiting via external components. Protection mechanisms include over-temperature shutdown, under-voltage lockout, and over-voltage clamping. The component is housed in a compact QFN-10 package suitable for surface mount technology.

Feature Summary

• Integrates a low on-resistance power MOSFET driven by an internal charge pump
• Provides adjustable output voltage rise slope and programmable current limiting
• Includes comprehensive protection against over-temperature, under-voltage, and over-voltage conditions

Applications

• Power distribution systems requiring surge current limitation
• Protection of output circuits from input transients
• Input protection against output short circuits and transients

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel configuration. Confirm RoHS compliance status through official documentation. Check the latest manufacturer lifecycle status as this series may be designated as not recommended for new designs. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target application.

Selection Notes

Select this component when a single-channel load switch with programmable protection is required. Consider the 4 V to 6 V input voltage range and the need for adjustable soft-start and current limits. Evaluate the thermal performance based on the integrated MOSFET resistance and expected load currents. Verify compatibility with the system's control logic and fault signaling requirements.
