High-Performance Isolated CAN Transceiver
NSI1042 is an isolated CAN transceiver, fully compatible with ISO11898-2 standard. NSI1042 integrates a two-channel digital isolator and a high-performance CAN transceiver. The digital isolator uses silicon oxide isolation based on NOVOSENSE capacitance isolation technology. Highly integrated solutions simplify system design and improve reliability. NSI1042 is UL1577-qualifed for safety, and support 5kVrms dielectric strength, while providing high electromagnetic immunity and low radiation. NSI1042 supports CAN FD and Data rate of up to 5Mbps, and can support at least 110 CAN nodes. NSI1042 is designed with thermal protection and transmission data dominant timeout protection.
