Description
The 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 devices also have a
hardware-selectable silent mode that disables the transmitter.
Designed for harsh CAN and DeviceNet environments, IL41050T
transceivers have transmit data dominant time-out, 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.
