MCZ33996EKR2

Overview

The MCZ33996EKR2 is a 16-channel low-side power switch IC manufactured by NXP Semiconductors. It operates within a supply voltage range of 5 V to 27 V and utilizes SMARTMOS technology for efficient load control. The device features an output current capacity of 350 mA per channel, with a maximum on-resistance of 1.1 Ohms. Current limiting ranges from 900 mA to 2.5 A, while typical rise and fall times are capped at 10 us. Designed for automotive environments, it functions reliably between -40 C and +125 C in a SOIC-32 package.

Feature Summary

Integrates 16 independent low-side open-drain MOSFET outputs using SMARTMOS technology for optimized power dissipation.
Provides comprehensive protection mechanisms including over-current, over-temperature, and over/under-voltage safeguards.
Enables precise load management through 24-bit SPI communication supporting PWM modulation and diagnostic feedback.

Applications

Automotive diesel engine management systems
Valve driver circuits
Inductive load switching applications

Procurement Notes

Verify component authenticity against official NXP documentation due to end-of-life status. Confirm package integrity and moisture sensitivity levels prior to assembly. Ensure design compatibility with existing SPI interfaces and thermal requirements for the specified operating temperature range.

Selection Notes

Select this component for designs requiring high-density low-side switching with integrated diagnostics. Evaluate thermal performance based on the 1.1 Ohm resistance and 1.7 W power dissipation limits. Consider the 24-bit SPI interface for complex control logic and ensure voltage margins align with the 5 V to 27 V operational window.

Part Context

This part belongs to the MC33996 series of smart power switches designed for robust automotive applications. It serves as a critical interface between microcontrollers and high-power loads, reducing system complexity by handling fault detection and protection directly on-chip.

Replacement Considerations

Check for direct substitutes within the MC33996 family or compatible NXP low-side switch portfolios. Verify pinout and electrical parameter equivalence before transitioning to alternative components.
