MCZ34670EG

Overview

The MCZ34670EG is a power management integrated circuit (PMIC) designed for i.MX50 and i.MX53 processors. It provides a low-cost solution for embedded applications without battery chargers, supporting single or multi-cell lithium batteries with external charger integration. The device features six multimode buck regulators, an LDO array, and a boost converter. It includes hardware programmable power sequencing, an ADC core, and interfaces like SPI/I2C. Packaged in a 130-pin MAPBGA, it supports industrial and consumer electronics.

Feature Summary

• Integrates multiple voltage regulation stages including buck, LDO, and boost converters to support complex processor power domains.
• Features hardware-programmable power sequencing to ensure correct startup order for connected system components.
• Includes an internal analog-to-digital converter (ADC) for monitoring chip temperature and battery voltage.
• Supports flexible battery configurations through easy connection to external chargers.

Applications

• Industrial control systems
• Surround view camera systems
• Embedded consumer electronics

Procurement Notes

Verify the specific package variant and environmental compliance status before ordering. Confirm that the target application does not require an integrated battery charger, as this component is optimized for external charging solutions. Ensure compatibility with the i.MX50 or i.MX53 processor family power requirements.

Selection Notes

Select this PMIC when designing systems based on NXP i.MX50 or i.MX53 processors requiring a consolidated power solution. It is suitable for applications needing multiple regulated rails and hardware sequencing without the complexity of battery management circuits. Consider the 130-pin MAPBGA footprint during PCB layout.

Part Context

This component belongs to the MC34709 series of power management ICs from NXP Semiconductors. It is specifically engineered to interface with i.MX50 and i.MX53 application processors, providing the necessary voltage rails and control logic for stable system operation in portable and industrial devices.

Replacement Considerations

Check for direct pin-compatible replacements within the MC34709 family. Verify if newer revisions offer improved thermal performance or updated regulatory compliance while maintaining functional equivalence for the i.MX5x platform.
