MP5034GJ-P

Overview

The MP5034GJ-P is a USB switch IC and charging port controller from Monolithic Power Systems. It operates within a supply voltage range of 3.6 V to 14 V and draws a typical operating current of 250 uA. The device supports Quick Charge 3.0, BC1.2 DCP, Divider, and 1.2V/1.2V modes without external intervention. It features input overvoltage protection and overtemperature protection. The component is housed in an 8-pin TSOT-23 package and is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates automatic detection for multiple fast-charging protocols including QC 3.0 and BC1.2 DCP.
• Provides comprehensive protection against input overvoltage and excessive temperature.
• Includes input discharge functionality when switching from high to low voltage states.

Applications

• USB charging port controllers
• Portable electronic devices
• Power banks

Procurement Notes

Verify the specific suffix 'P' corresponds to the required tape-and-reel packaging configuration during procurement. Confirm that the 8-pin TSOT-23 footprint matches the design layout. Ensure compatibility with the specified 3.6 V to 14 V input range for the target application environment.

Selection Notes

Select this component for designs requiring integrated protocol detection without external microcontroller intervention. It is suitable for applications needing support for both standard BC1.2 and proprietary fast-charging standards like QC 3.0 within a compact surface-mount package.

Part Context

This part belongs to the MP5034 series of USB switch ICs manufactured by Monolithic Power Systems. The series focuses on minimizing external component count while providing robust power management and charging negotiation capabilities for USB interfaces.

Replacement Considerations

MP5034GJ-Z is a verified substitute offering identical electrical characteristics but packaged in reels of 3000 units instead of 500.
