NSiP1042 Signal Isolated CAN Transceiver With Integrated DC to DC Converter Datasheet (EN) 1.0 Product Overview NSiP1042 is a high reliability isolated controller area network(CAN) physical layer transceiver with integrated DC to DC converter. The isolated DC-DC converter provides output power using on-chip transformer. The feedback PWM signal is sent to primary side by a digital isolator based on Novosense capacitive isolation technology. Both devices are safety certified by UL1577, supporting 5kVrms insulation withstand voltage, while the high integrated solution can help to simplify system design and improve reliability. The Bus pins of NSiP1042 are protected from ±5kV system level ESD to GND2 on Bus side. The data rate of the NSiP1042 is up to 5Mbps. The NSiP1042 provides thermal protection and transmit data dominant time out function.
