MCZ33991EG

Overview

The MCZ33991EG is a low-side load controller manufactured by NXP USA Inc., designed for automotive applications. It features an SPI interface and provides 8 output channels with SMARTMOS technology. The device operates at a supply voltage of up to 27V and supports a continuous current of 1.2A per channel. Packaged in a WSOIC-32, it includes protection against over-current, over-temperature, and over/under-voltage conditions.

Feature Summary

Provides multiple channels of open-drain MOSFET output switching using SMARTMOS technology for low RDSON and low power dissipation.
Offers comprehensive load and IC protection including over-current, over-temperature, and over/under-voltage safeguards.

Applications

Automotive Diesel Engine Management
Valve Driver

Procurement Notes

Verify the specific suffix 'EG' against official datasheets to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for WSOIC-32 packages. Confirm that the 8-channel configuration meets system requirements instead of higher-channel alternatives.

Selection Notes

Select this component when an 8-channel low-side switch is required for resistive or inductive loads. It is suitable for designs needing SPI control and integrated protection features. Consider the 1.2A per channel rating for load capacity planning.

Part Context

This part belongs to NXP's low-side switches portfolio, which utilizes SMARTMOS technology for efficient load control. These devices are engineered for automotive environments, providing reliable switching for engine management systems and other vehicle subsystems requiring robust ground-side control.

Replacement Considerations

Check for MCZ33996EK if more output channels are needed. Verify pinout compatibility before substituting with other low-side switches from the MC3399x family.
