NVE Corporation's IL41050 is a galvanically isolated, high-speed CAN (Controller Area Network) transceiver, designed as the interface between the CAN protocol controller and the physical bus. The IL41050 provides isolated differential transmit capability to the bus and isolated differential receive capability to the CAN controller via NVE’s patented IsoLoop™ spintronic Giant Magnetoresistance (GMR) technology.
Advanced features facilitate reliable bus operation. Unpowered nodes do not disturb the bus, and a unique non-volatile programmable power-up feature prevents unstable nodes. The device also has a hardware-selectable silent mode that disables the transmitter.
Designed for harsh CAN and DeviceNet environments, the IL41050T transceiver has transmit data dominant timeout, bus pin transient protection, thermal shutdown protection, and short-circuit protection. Unique edge-triggered inputs improve noise performance. Unlike optocouplers or other isolation technologies, IsoLoop isolators have indefinite life at high voltage.
