MP5014AGJ-P

Overview

The MP5014AGJ-P is a programmable current limit switch IC from Monolithic Power Systems, designed for power distribution applications. It operates within a supply voltage range of 10 V to 13.8 V and supports a maximum load current of 5 A. The device features an integrated N-channel power FET with a typical on-resistance of 36 mΩ. Key protection mechanisms include input under-voltage lockout, over-temperature shutdown, and output over-voltage clamping at 15 V (with a 22 V absolute maximum rating). The output rise time slope is adjustable via an external capacitor, and the current limit threshold is programmable through an external resistor.

Feature Summary

• Programmable current limiting capability allows customization of fault protection thresholds
• Adjustable output voltage rise slope controls inrush current during startup
• Integrated high-side protection against short circuits, over-temperature, and over-voltage conditions

Applications

• Power distribution systems requiring programmable load protection
• Industrial equipment power management modules
• Automotive electronic control unit (ECU) power switching

Procurement Notes

Verify the specific suffix 'GJ' corresponds to the TSOT-23-8 package and lead-free status as defined in the official datasheet. Confirm that the ordering code matches the required tape-and-reel or cut-tape format. Ensure compatibility with the intended operating temperature range of -40°C to +125°C. Cross-reference the pinout configuration with the target PCB layout to avoid interface mismatches.

Selection Notes

Select this component when a 12V nominal system requires robust, programmable overload protection. It is suitable for designs needing controlled turn-on slew rates to prevent bus collapse. Consider the thermal dissipation capabilities given the 1.25 W power dissipation rating. Evaluate the external component requirements for setting the current limit and soft-start timing against board space constraints.

Part Context

This part belongs to the MP5014A series of power switch ICs. It serves as a protective element between the power source and the load, preventing damage from electrical faults. The device integrates the control logic and power stage into a single compact package, simplifying the design of reliable power distribution networks compared to discrete solutions.

Replacement Considerations

The MP5000S is identified as a previous generation alternative but is not recommended for new designs. Designers should transition to the MP5014A series for updated performance and availability. Verify pin-to-pin compatibility if substituting in existing layouts.
