Overview
The MCZ33879EKR2 is a configurable octal serial power switch manufactured by NXP USA Inc. It features eight N-channel outputs with a maximum current of 600mA per channel. The device operates within a load voltage range of 5.5V to 26.5V and a supply voltage of 3.1V to 5.5V. It utilizes a 1:8 input-to-output ratio controlled via a 16-bit SPI interface. The typical on-resistance is 750 milliohms at 25°C. The component is housed in a 32-SOIC-EP package and supports an operating junction temperature from -40°C to 150°C.
Feature Summary
- Configurable high-side or low-side switching architecture for versatile load control
- Integrated fault protection including fixed current limiting, open load detection, and overvoltage protection
- Direct microcontroller interface compatibility through standard SPI communication protocol
Applications
- Automotive body electronics load distribution
- Industrial general-purpose load switching systems
- White goods and appliance control interfaces
Procurement Notes
Verify the specific ordering suffix EKR2 against official NXP documentation to confirm reel packaging specifications. Confirm that the component status remains discontinued as indicated by current distributor records. Ensure compliance with RoHS3 standards and check moisture sensitivity levels prior to storage and handling procedures.
Selection Notes
Select this component when eight independent channels are required for driving resistive or inductive loads. The integrated diagnostic features simplify system design by reducing external protection circuitry needs. Consider the thermal performance requirements given the SOIC-EP package and the specified junction temperature range for industrial environments.
Part Context
This part belongs to the MCZ33879 family of smart power switches designed for automotive and industrial applications. It replaces older discrete switching solutions by integrating control logic and power MOSFETs into a single unit. The device supports hardware configuration options to adapt to various system architectures without software overhead.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with legacy parts if direct replacement is required.
