MC33879APEK Configurable Octal Serial Switch 1:4 N-Channel 600mA
The MC33879APEK is a high-performance, 8-output configurable high-side/low-side switch manufactured by NXP Semiconductors. Housed in a 32-pin WSOIC (HSOP) package with an exposed pad, this device operates over a wide supply voltage range of 5.5V to 27.5V and supports an industrial/automotive temperature range of -40°C to +125°C. It features a 16-bit SPI interface for MCU control and fault reporting, with two dedicated PWM inputs for direct pulse-width modulation control. Built on NXP's SMARTMOS technology, it integrates CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs for robust load driving.
Key Features & Application Scenarios
This octal switch delivers 0.6A to 1.2A per output with a typical RDS(ON) of 0.75Ω at 25°C, supporting both high-side and low-side configurations. It includes output voltage clamping (+45V low-side, -20V high-side) for inductive load protection, open-load detection with disable capability for LED applications, and internal reverse battery protection. Additional features include 5µA maximum standby current at 13V, short-circuit detection with automatic retry, and independent overtemperature protection. Ideal for automotive body electronics, industrial control systems, and embedded designs, it drives solenoids, relays, DC motors, incandescent lamps, and LED arrays, providing centralized load management and fault diagnostics.
