MP5036AGJ-P

Overview

The MP5036AGJ-P is a current limit switch with overvoltage protection, manufactured by Monolithic Power Systems. It operates within a continuous input voltage range of 2.9V to 14V and withstands transient voltages up to 26V. The device features a fixed overvoltage clamp threshold at 15V. It integrates a power FET with an on-resistance of 43mΩ. The current limit is adjustable via an external resistor or fixed at 2.5A when the ILIMIT pin is floating. Soft-start time is programmable through the DV/DT pin. The component is housed in a TSOT23-6 package and supports surface mount installation.

Feature Summary

• Integrates overvoltage protection with a fixed 15V clamp threshold for output safety
• Features programmable soft-start functionality to control surge current during startup
• Provides adjustable or fixed current limiting capabilities based on external resistance configuration
• Includes automatic recovery from overcurrent conditions and thermal shutdown protection

Applications

• Protection of output circuits against input transients
• Input protection against short circuits and output transients
• Surge current limitation during system startup sequences

Procurement Notes

Verify the specific suffix designation to confirm the tape and reel packaging format required for automated assembly processes. Ensure that the ordering information matches the exact package type and environmental compliance standards specified in the official datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust protection against input voltage spikes and output short circuits. The integrated overvoltage clamp eliminates the need for external clamping diodes in many applications. Consider the adjustable current limit feature for customizing load protection levels. The wide operating temperature range makes it suitable for industrial environments where thermal stability is critical for reliable operation.

Part Context

This part belongs to the MP5036 series of power distribution ICs from Monolithic Power Systems. It is designed as a high-side switch solution that combines current limiting and overvoltage protection in a single compact package. The series targets applications requiring efficient power management and circuit protection without complex external component networks.
