MP5032GJ-Z

Overview

The MP5032GJ-Z is a USB switch IC and Quick Charge 3.0 controller from Monolithic Power Systems, housed in an 8-lead TSOT-23 package. It operates within a wide input voltage range of 3.6 V to 14 V and supports continuous output currents up to 3 A. The device features a low on-resistance power MOSFET with a maximum RDS(on) of 40 mOhms. Key electrical parameters include a quiescent current of 250 uA and a power dissipation rating of 1.89 W. It functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates a USB current-limiting switch with charging port identification circuitry for automatic mode detection.
• Supports QC 3.0, BC1.2 DCP, Divider, and 1.2V/1.2V modes without external intervention.
• Provides linear line drop compensation specifically for 5 V outputs to maintain voltage stability.
• Includes comprehensive protection mechanisms such as hiccup current limiting, input overvoltage protection, and overtemperature shutdown.

Applications

• USB charging port controllers for mobile devices
• Fast charging solutions compatible with QC 3.0 specifications
• Power management systems requiring integrated USB load switching

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance when sourcing. Confirm the TSOT-23-8 package dimensions match your PCB footprint requirements. Ensure the design accommodates the specified 1.89 W power dissipation limits under maximum load conditions. Cross-reference the operating temperature range against your target application environment to guarantee reliability.

Selection Notes

Select this component for applications requiring a compact solution that combines USB switching and fast-charge protocol handling. It is suitable for designs needing support for multiple charging standards including QC 3.0 and BC1.2. Consider the 3 A current capability and low on-resistance for efficient power delivery. The integrated protection features reduce the need for external safety components.

Part Context

This part belongs to the MP5032 series of USB controllers manufactured by Monolithic Power Systems. It is designed to simplify USB charging infrastructure by integrating switch and control functions. The device is commonly used in consumer electronics where space constraints and multi-standard charging support are critical design factors.

Replacement Considerations

The MP5032GJ-P is a verified alternative within the same product family, offering identical functional specifications. Both variants share the same TSOT-23-8 package and electrical performance characteristics. Verify packaging preferences when substituting, as the suffix denotes different reel or cut-tape configurations rather than functional changes.
