11.2 Typical Application

The ISOW1044 device is suitable for applications that have limited board space and desire more integration. It is also suitable for very high voltage applications, where power transformers meeting the required isolation specifications are bulky and expensive. The device can be used in applications with a host micro-controller or FPGA that includes the link layer portion of the CAN protocol. #GUID-FC10236D-B68C-4E62-895D-4190F67269B8 shows a typical application configuration for 5 V controller applications. The bus termination is shown for illustrative purposes. The ISOW1044 device meets 8 kV contact ESD (Electrostatic discharge) per IEC 61000-4-2 standalone with no external components on bus. If the application requires the usage of Common mode choke (CMC) , then use of Transient voltage suppressor (TVS) is a must to achieve 8kV IEC ESD.
