3. Device introduction
The ISO1042-Q1 device is a galvanically isolated Controller Area Network (CAN) transceiver compliant to the ISO11898-2 (2016) standard specification. The ISO1042-Q1 device provides ±70-V DC bus fault protection and a ±30-V common-mode voltage range. The device supports data rates up to 5Mbps in CAN FD mode, enabling faster payload transfers compared to classic CAN. The device features a silicon dioxide (SiO2) insulating barrier and can withstand voltages of 5000VRMS and an operating voltage of 1060VRMS. Electromagnetic compatibility has been significantly enhanced to enable system-level ESD, EFT and surge and emissions compliance.
