MCZ33880EWR2

Overview

The MCZ33880EWR2 is a power switch and driver integrated circuit manufactured by NXP USA Inc. It features an N-channel output configuration with a single input to eight outputs ratio. The device supports load voltages from 5.5V to 24.5V and operates on a supply voltage of 4.75V to 5.25V. It delivers a maximum output current of 800mA per channel with a typical on-resistance of 550 milliohms. Communication is handled via an SPI interface. The component is housed in a 32-BSSOP package and functions within a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates eight independent high-side or low-side N-channel power switches controlled through a serial peripheral interface.
• Provides comprehensive fault protection mechanisms including fixed current limiting, open load detection, and overvoltage safeguards.

Applications

• Industrial distributed I/O systems requiring reliable power switching
• Automotive electronic control units for actuator and sensor power management
• General-purpose load driving applications in harsh environments

Procurement Notes

Verify the specific ordering suffix EWR2 against official NXP documentation to confirm tape-and-reel packaging specifications. Confirm that the component status remains active for new designs, as availability may vary. Ensure compatibility with existing SPI communication protocols and thermal management requirements for the 32-SOIC package before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple isolated power channels controlled digitally. The wide operating temperature range suits industrial and automotive environments. Consider the 800mA current limit and 550 milliohm resistance for load matching. Verify that the SPI interface aligns with the host controller's capabilities and that the 32-pin package fits the board layout constraints.

Part Context

This part belongs to the MCZ33880 family of power switches designed for robust performance in demanding applications. The family offers scalable solutions for managing multiple loads with integrated diagnostics. The MCZ33880EWR2 variant specifically provides the reel packaging option for automated assembly processes while maintaining the core electrical characteristics of the series.

Replacement Considerations

Check NXP datasheets for direct pin-to-pin compatible alternatives within the same product family. Verify that any substitute maintains identical SPI command sets and fault protection behaviors to ensure system stability without redesigning the control logic or power stage.
