Procurement Notes

Verify the specific suffix 'EK' against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target i.MX processor variant before procurement. Confirm that the required power rail count matches the integrated regulator availability. Check for any regional compliance certifications associated with this specific marking code.

Selection Notes

Select this PMIC when designing systems based on i.MX50 or i.MX53 processors that require a consolidated power solution. It is suitable for applications needing integrated USB PHY support and resistive touch input handling. Consider this component if the design benefits from programmable power sequencing and onboard analog-to-digital conversion for system monitoring.

Part Context

This component belongs to NXP's portfolio of power management solutions tailored for embedded processing platforms. It complements the i.MX50 and i.MX53 application processors by providing necessary voltage regulation and system control functions in a compact MAPBGA package. The device aims to reduce board space and simplify power architecture for multimedia and industrial applications.

Replacement Considerations

Check for direct cross-reference part numbers within the MC347xx series. Verify pinout and register compatibility if substituting with other i.MX-specific PMICs. Ensure alternative components support the same processor families and feature sets.
