Abstract

System Basis Chips (SBCs) from TI offer many benefits to a system by integrating power electronics, communication transceivers, robust protection features, and a unified control system that ties all of the functionality into one package. TI SBCs either contain one LIN bus, one CAN bus, or both a CAN and LIN bus, but that is not the full scope of all potential SBC use cases across various applications. If an additional communication transceiver is required but not offered by the SBC, what options does the designer have? Luckily TI’s designers thought of this exact scenario and integrated a general field output (GFO) pin to aid in transceiver channel expansion among other features. Utilizing the GFO pin on TI SBCs, primarily the TCAN28xx-Q1 and TCAN24xx-Q1 device families, allow a designer to add additional transceiver communication channels to system design.
