Overview

Our integrated circuits and reference designs help you create compact and robust zone control modules that can drive multiple loads, reliably transmit and receive data, and reduce the power consumption within the vehicle. Explore our broad portfolio of DC/DC converters, LDOs, power management ICs, CAN, LIN and Ethernet transceivers, high side switches, motor drivers, smart diodes, and more to optimize your next zone control module.

Design requirements

  • Fuse replacement with high side switches to optimize vehicle cabling
  • Effective communication to other vehicle modules over multiple communication standards (CAN, LIN, Ethernet)
  • Careful balance of thermal performance and PCB size
  • Optimized EMC performance to meet emissions and immunity standards
