MP5017AGD-P

Overview

The MP5017AGD-P is a power distribution IC from Monolithic Power Systems featuring a single output channel. It operates within a supply voltage range of 3 V to 5.5 V and supports an output current up to 5 A with a fixed current limit of 2.4 A. The device incorporates over-voltage clamp and reverse blocking capabilities for circuit protection. Key electrical parameters include a maximum on-resistance of 45 mOhms and a maximum turn-on time of 160 us. It dissipates up to 3.125 W of power and functions reliably across an extended temperature range from -40 C to +125 C.

Feature Summary

• Integrates over-voltage clamp and reverse blocking mechanisms to protect downstream loads from transient spikes and polarity reversals.
• Provides precise current limiting at 2.4 A to prevent damage during short-circuit or overload conditions.
• Features low on-resistance to minimize conduction losses and improve system efficiency in power distribution networks.

Applications

• Power distribution in portable electronic devices requiring robust load protection
• Peripheral power switching in industrial control systems operating within standard voltage rails
• Protection circuits for high-side or low-side load switching applications

Procurement Notes

Verify the specific suffix 'P' against official manufacturer documentation to confirm packaging configuration, as ordering suffixes define physical shipping formats rather than functional changes. Ensure compatibility with the required QFN-12 footprint and thermal management requirements for the target application environment.

Selection Notes

Select this component when a fixed 2.4 A current limit is sufficient for the load profile. It is suitable for applications requiring integrated over-voltage and reverse polarity protection without external discrete components. Consider alternative MPS models if programmable current limits or higher voltage ratings are necessary for the design.

Part Context

This part belongs to the MP5017 series of power switch ICs designed for efficient power distribution. It serves as a compact solution for managing power delivery in space-constrained designs. The series emphasizes reliability through integrated protection features, making it a standard choice for protecting sensitive electronics in consumer and industrial equipment.

Replacement Considerations

MP5017AGD-Z is a verified substitute within the same series offering identical electrical specifications and functionality, differing primarily in reel packaging quantity.
