High-Performance Isolated CAN Transceiver
NSi1050 is an isolated CAN transceiver, fully compatible with ISO11898-2 standard. NSi1050 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. NSi1050 is UL1577-qualifed for safety, and support 5kVrms dielectric strength, while providing high electromagnetic immunity and low radiation. NSi1050 supports Data rate of up to 1Mbps and can support at least 110 CAN nodes. NSi1050 is designed with thermal protection and transmission data dominant timeout protection.
