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.

*U.S. Patent number 5,831,426; 6,300,617 and others.

Notes:
1. The TxD input is edge sensitive. Voltage magnitude of the input signal is specified, but edge rate specifications must also be met.
2. The maximum time allowed for a logic transition at the TxD input is 1 μs.
3. Uniform magnetic field applied across the pins of the device. Cross-axis multiplier effective when field is applied perpendicular to the pins.
4. If VDD2 falls below the specified failsafe supply voltage, RxD will go High.
Electrostatic Discharge Sensitivity
This product has been tested for electrostatic sensitivity to the limits stated in the specifications. However, NVE recommends that all integrated
circuits be handled with appropriate care to avoid damage. Damage caused by inappropriate handling or storage could range from performance
degradation to complete failure.
Electromagnetic Compatibility
The IL41050 is fully compliant with generic EMC standards EN50081, EN50082-1 and the umbrella line-voltage standard for Information
Technology Equipment (ITE) EN61000. The IsoLoop Isolator’s Wheatstone bridge configuration and differential magnetic field signaling ensure
excellent EMC performance against all relevant standards. NVE conducted compliance tests in the categories below:
EN50081-1
Residential, Commercial & Light Industrial
Methods EN55022, EN55014
EN50082-2: Industrial Environment
Methods EN61000-4-2 (ESD), EN61000-4-3 (Electromagnetic Field Immunity), EN61000-4-4 (Electrical Transient Immunity),
EN61000-4-6 (RFI Immunity), EN61000-4-8 (Power Frequency Magnetic Field Immunity), EN61000-4-9 (Pulsed Magnetic
Field), EN61000-4-10 (Damped Oscillatory Magnetic Field)
ENV50204
Radiated Field from Digital Telephones (Immunity Test)
Immunity to external magnetic fields is higher if the field direction is “end-to-end” (rather than to “pin-to-pin”) as shown in the
diagram at right.
