Tiny reinforced isolated transceivers boost bus fault protection


TEXAS INSTRUMENTS ISO1042 and ISO1042-Q1 isolated CAN FD isolated Controller Area Network (CAN) flexible data rate (FD) transceivers combine high bus fault protection, high common-mode transient immunity (CMTI) and low electromagnetic emissions into a 35% smaller package. Products help better protect low-voltage circuits and increase communication throughput in industrial applications. With an 18% higher working voltage of 1,000Vrms and a withstand voltage of 5,000Vrms, devices provide longer lifetimes, resulting in improved system reliability. Product’s high bus fault protection of ±70 V provides a 20% higher short-to-dc margin, while protecting 12-, 24- and 48V battery or power-supply systems during high-voltage shorts.
