MP5010ADQ-LF-P

Overview

The MP5010ADQ-LF-P is a programmable current-limit switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 3V to 18V and supports load currents from 1A to 5A. The device integrates an over-voltage clamp for protection. It is housed in a QFN-10 package measuring 3mm x 3mm. The component functions as a power distribution controller with adjustable current limiting capabilities.

Feature Summary

• Integrates an over-voltage clamp mechanism to protect downstream loads from transient voltage spikes exceeding safe operating limits.
• Features a fully programmable current limit threshold, allowing precise adjustment of maximum output current via external components.

Applications

• Power distribution units requiring programmable current protection
• Over-voltage protected load switching in industrial systems
• Current-limited power rails in embedded electronics

Procurement Notes

Verify the specific suffix 'ADQ' against official datasheets to confirm pinout and thermal pad configuration. Ensure the LF designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the manufacturer's latest documentation to validate availability status before finalizing procurement plans.

Selection Notes

Select this component when a wide input voltage range up to 18V is required alongside high current handling up to 5A. The integrated over-voltage clamp simplifies design compared to discrete solutions. Ensure the application environment stays within the specified -40°C to +125°C operating temperature range for reliable performance.

FAQ

What is the function of the over-voltage clamp?

The over-voltage clamp protects the load by limiting the output voltage to a safe level during transient events or input surges.

How is the current limit adjusted?

The current limit is programmable, typically set by connecting a resistor between the ILIM pin and ground, as defined in the official datasheet.
