MCZ33298EGR2

Overview

The MCZ33298EGR2 is an eight-channel low-side power switch manufactured by NXP USA Inc. It integrates an 8-bit serial-in shift register to control eight independent N-channel outputs, each capable of switching up to 3A. The device operates within a supply voltage range of 8V to 18V and utilizes a standard serial interface for command input. Packaged in a 24-SOIC housing, it is designed for robust load management in automotive environments.

Feature Summary

• Integrates an 8-bit serial-in shift register for efficient control of multiple loads
• Provides individual current limiting and thermal protection for each output channel
• Features diagnostic feedback capabilities to report open-load and short-circuit conditions

Applications

• Automotive lighting systems including interior and exterior lamps
• Power distribution units for managing multiple peripheral loads
• General purpose load switching in vehicle body electronics modules

Procurement Notes

Verify the specific suffix EGR2 against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Confirm end-of-life status as this component may be obsolete or superseded by newer alternatives in the MCZ3329x family. Ensure compatibility with existing serial control logic levels before integration into new designs.

Selection Notes

Select this component when designing systems requiring independent control of eight low-side loads via a simple serial interface. It is suitable for applications needing moderate current handling per channel with integrated protection features. Consider pinout compatibility and thermal performance requirements relative to the 24-SOIC package constraints.

Part Context

This part belongs to the MCZ3329x series of smart power switches from NXP. These devices are engineered for automotive body applications where reliable load switching and diagnostics are critical.
