MC33879APEK Configurable Octal Switch
The MC33879APEK from NXP Semiconductors is a configurable 8-channel (Octal) high-side/low-side power switch designed for robust automotive and industrial load management. Housed in a thermally enhanced 32-pin SOIC-W (HSOP) package, this device integrates eight N-channel power MOSFETs that can be individually configured via hardware pin strapping as either high-side (source) or low-side (sink) drivers. Operating from a wide 5.5 V to 27.5 V supply (VPWR) with a separate 3.1 V to 5.5 V logic supply (VDD), it is engineered to control a variety of loads—including solenoids, lamps, LEDs, and small DC motors—while providing comprehensive diagnostic feedback via a 16-bit SPI interface. With a typical on-resistance of 0.75 Ω and per-channel current limiting between 0.6 A and 1.2 A, it offers a balance of drive capability and protection. The chip is AEC-Q100 qualified for the -40°C to +125°C automotive temperature range, ensuring reliable performance in harsh electrical environments.
MC33879APEK Applications
1. Automotive Body Electronics: Door module controllers (window lifts, mirror adjusters), seat control units, and interior lighting (dome, map lights) in 12V vehicle systems.
2. Industrial Actuator Control: Driving solenoids, small relay coils, and indicator lamps in PLC digital output modules and factory automation panels.
3. Motor Drive Systems: H-bridge configuration for small DC motors or stepper motor winding control in HVAC dampers and automotive actuators.
4. Power Distribution Modules: Centralized load switching in automotive fuse boxes or junction blocks requiring SPI-based diagnostics and reporting.
Alternativeoctal power switch
● MC33880DWB (NXP): A similar 8-channel configurable serial switch with SPI, offering comparable functionality in a different package and pinout, often used in similar automotive power distribution applications.
● TLE6240GP (Infineon): A 16-channel low-side smart switch with advanced diagnostics and PWM capability, ideal for applications requiring higher channel density but lacking high-side configurability.
● VND5T100AJ (STMicroelectronics): A dual high-side driver with analog current sense, targeting specific high-current, high-side applications like direct lamp driving where fewer channels are needed.
