MC33879APEKR2 configurable 8-output serial switch 1:4 N-Channel 600mA
The MC33879APEKR2 is a highly configurable 8-output serial switch that operates in both high-side and low-side configurations, offering exceptional design flexibility. Built on SMARTMOS technology, this device integrates CMOS logic, bipolar analog circuitry, and DMOS power MOSFETs to drive inductive, incandescent, or LED loads directly from a microcontroller . It features a 16-bit Serial Peripheral Interface (SPI) for control and fault reporting, with two outputs capable of direct PWM control. Housed in a 32-pin SOIC wide package with an exposed pad, the device supports a wide power supply range of 5.5 V to 27.5 V and operates reliably from -40°C to +125°C, making it ideal for harsh environments.
MC33879APEKR2 Applications
This switch is specifically designed for automotive body electronics, including solenoid drivers, relay controls, actuators, and stepper and brush DC motors . It is also widely used in industrial automation systems, HVAC controls, power distribution modules, and LED lighting control . Its ability to be configured as either high-side or low-side allows H-bridge formation for bidirectional motor control, making it suitable for power seat adjustments, window lifts, and fuel pump control in modern vehicles.
