It provides 2500 Vrms isolation using a silicon dioxide (SiO2) insulation barrier, with 50 kV\/us typical common-mode transient immunity. The device supports CAN signaling rates up to 1 Mbps with 150 ns typical loop delay, ensuring reliable timing margins. Bus fault protection extends from -27V to 40V, and the common-mode range is -12V to 12V. The I\/O side supports both 3.3V and 5V MCU logic levels. Safety certifications include UL 1577, VDE 0884-17, IEC 60601-1 (medical), and IEC 61010-1.","working_principle":"The ISO1050DUBR integrates a CAN transceiver with galvanic isolation using a SiO2 dielectric barrier between the logic side (VCC1) and the bus side (VCC2). On the logic side, TXD and RXD interface with the CAN controller at 3.3V or 5V logic levels. On the bus side, the transceiver drives CANH and CANL differentially. The SiO2 barrier provides both electrical isolation and level translation. The driver dominant timeout feature detects if TXD is stuck dominant for longer than the timeout period and releases the bus, preventing network lockup. Fail-safe outputs ensure RXD defaults to a recessive (high) state when the input is floating or VCC1 is unpowered. Overtemperature shutdown on the bus side protects against thermal damage. The device is designed for use with an isolated DC-DC converter to provide complete galvanic isolation of the CAN node.","pin_description":"
