MCZ33880EW

Overview

The MCZ33880EW is a power switch and driver manufactured by NXP USA Inc., designed for high-side or low-side load control applications. It features an N-channel output configuration with eight independent channels, providing a maximum output current of 800mA per channel. The device operates within a load voltage range of 5.5V to 24.5V and requires a supply voltage (Vcc/Vdd) between 4.75V and 5.25V. Communication is managed via an SPI interface with a 1:8 input-to-output ratio. Key electrical parameters include a typical on-resistance of 550 milliohms. The component supports fault protection mechanisms such as fixed current limiting, open-load detection, and overvoltage protection. It is housed in a 32-BSSOP package with a width of 7.50mm and functions reliably across a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides multi-channel load switching capability with integrated diagnostic features including open-load detection and overvoltage protection.
• Utilizes SmartMOS technology to achieve low on-resistance and reduced power consumption for resistive and inductive loads.
• Enables precise digital control through a serial peripheral interface (SPI) communication protocol.

Applications

• Automotive engine management systems
• Diesel engine control units
• Valve drivers for automotive applications

Procurement Notes

Verify the obsolete status of this component before design finalization, as it is marked as discontinued. Confirm that alternative solutions from the manufacturer are available for long-term production needs. Ensure compatibility with existing SPI interfaces and voltage requirements during the transition process. Check for any specific handling instructions related to the 32-SOIC package and moisture sensitivity level.

Selection Notes

Select this component when designing systems requiring multiple independently controlled high-side or low-side switches with diagnostic feedback. It is suitable for applications needing robust fault protection against overcurrent and open loads. Consider the thermal performance and package constraints when integrating into dense circuit boards. Verify that the operating voltage ranges align with the system's power supply architecture.
