MCZ33880EGR2

Overview

The MCZ33880EGR2 is a power switch and driver manufactured by NXP USA Inc., featuring an 1:8 input-to-output ratio. It provides eight N-channel outputs with a maximum current of 800mA per channel. The device operates on a supply voltage range of 4.75V to 5.25V and supports load voltages from 5.5V to 24.5V. It utilizes an SPI interface for control and is housed in a 28-SOIC package.

Feature Summary

• Integrates eight independent N-channel power switches controlled via a single serial peripheral interface (SPI) input.
• Includes comprehensive fault protection mechanisms such as fixed current limiting, open-load detection, and overvoltage protection.
• Supports flexible output configuration allowing operation as either high-side or low-side drivers.

Applications

• General purpose power distribution switching
• Load driving in automotive electronics
• Industrial control systems requiring isolated power management

Procurement Notes

Verify the specific package variant, as datasheets indicate both 28-SOIC and 32-BSSOP configurations for this part number family. Confirm RoHS compliance status and check for obsolete status notifications before finalizing procurement plans. Ensure the selected component matches the required pinout and thermal specifications for the target application.

Selection Notes

Select this component when a compact solution is needed to drive multiple loads using a single microcontroller interface. The SPI interface reduces pin count compared to parallel control schemes. Consider the 800mA output capability and the specific voltage ranges to ensure compatibility with the intended load requirements and system power architecture.

Part Context

This component belongs to the MCZ33880 series of power switches. It is designed for applications requiring efficient power management with minimal control lines. The series typically integrates protection features essential for robust electronic systems, distinguishing it from basic discrete transistor solutions.

Replacement Considerations

Check for direct substitutes within the MCZ33880 series that may offer different package options or updated manufacturing statuses. Verify pin compatibility and electrical specifications against alternative components from NXP or other manufacturers if the current part is obsolete.
