MC33879EK Description

Short technical summary and product information.

The MC33879EK from NXP Semiconductors is an 8-output, serial-controlled switch designed for power distribution applications. Utilizing SMARTMOS technology, it integrates CMOS logic, analog circuitry, and DMOS power MOSFETs to efficiently control various load types including inductive, incandescent, and LED loads.

 

This device operates with a supply voltage range of 3.1V to 5.5V and features an SPI interface for control and fault reporting, compatible with both 3.3V and 5.0V logic levels. Key electrical specifications include an output current limit of 600mA and a typical on-resistance of 750mΩ at 25°C. The MC33879EK offers flexible output configurations, supporting both high-side and low-side switching.

 

Protection features are integral to the MC33879EK, including fixed current limiting, open load detection, and overvoltage protection. It also incorporates independent overtemperature protection and internal reverse battery protection on the VPWR supply. The device is housed in a 32-SOIC-EP package with exposed pad, suitable for surface mounting, and operates within a temperature range of -40°C to 150°C (TJ).
