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.

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),

IL41050
Application Information
Power Supply Decoupling
Both VDD1 and VDD2 must be bypassed with 100 nF ceramic capacitors. These supply the dynamic current required for the isolator switching and
should be placed as close as possible to VDD and their respective ground return pins.
Dominant Mode Time-out and Failsafe Receiver Functions
CAN bus latch up is prevented by an integrated Dominant mode timeout function. If the TxD pin is forced permanently low by hardware or
software application failure, the time-out returns the RxD output to the high state no more than 765 μs after TxD is asserted dominant. The timer
is triggered by a negative edge on TxD. If the duration of the low is longer than the internal timer value, the transmitter is disabled, driving the
bus to the recessive state. The timer is reset by a positive edge on pin TxD.
If power is lost on Vdd2, the IL41050 asserts the RxD output high when the supply voltage falls below 3.8 V. RxD will return to normal
operation as soon as Vdd2 rises above approximately 4.2 V.
The Isolation Advantage
Battery fire caused by over or under charging of individual lithium ion cells is a major concern in multi-cell high voltage electric and hybrid
vehicle batteries. To combat this, each cell is monitored for current flow, cell voltage, and in some advanced batteries, magnetic susceptibility.
The IL41050 allows seamless connection of the monitoring electronics of every cell to a common CAN bus by electrically isolating inputs from
outputs, effectively isolating each cell from all other cells. Cell status is then monitored via the CAN controller in the Battery Management
System (BMS).
Another major advantage of isolation is the tremendous increase in noise immunity it affords the CAN node, even if the power source is a
battery. Inductive drives and inverters can produce transient swings in excess of 20 kV/μs. The traditional, non-isolated CAN node provides some
protection due to differential signaling and symmetrical driver/receiver pairs, but the IL41050 typically provides more than twice the dV/dt
protection of a traditional CAN node.

Programmable Power-Up
A unique non-volatile programmable power-up feature prevents unstable nodes. A state that needs to be present at node power up can be
programmed at the last power down. For example if a CAN node is required to “pulse” dominant at power up, TxD can be sent low by the
controller immediately prior to power down. When power is resumed, the node will immediately go dominant allowing self-check code in the
microcontroller to verify node operation. If desired, the node can also power up silently by presetting the TxD line high at power down. At the
next power on, the IL41050 will remain silent, awaiting a dominant state from the bus.
The microcontroller can check that the CAN node powered down correctly before applying power at the next “power on” request. If the node
powered down as intended, RxD will be set high and stored in IL41050’s non-volatile memory. The level stored in the RxD bit can be read
before isolated node power is enabled, avoiding possible CAN bus disruption due to an unstable node.
