Description

General part information

ISO1044 Series

The ISO1044B device is a galvanically-isolated controller area network (CAN) transceiver that meets the specifications of the ISO11898-2 (2016) standard. The ISO1044B device offers ±58-V DC bus fault protection and ±12-V common-mode voltage range. The device supports up to 5-Mbps data rate in CAN FD mode allowing much faster transfer of payload compared to classic CAN. This device uses a silicon dioxide (SiO2) insulation barrier with a withstand voltage of 3000 VRMSand a working voltage of 450 VRMS. Electromagnetic compatibility has been significantly enhanced to enable system-level ESD, EFT, surge, and emissions compliance. Used in conjunction with isolated power supplies, the device protects against high voltage, and prevents noise currents from the bus from entering the local ground. The ISO1044B device supports a wide ambient temperature range of –40°C to +125°C. The device is available in the small SOIC-8 (D) package which significantly reduces the solution size compared to a traditional approach using optocouplers to isolate the CAN transceiver.
