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, IL41050 T
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.

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 failu re.
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),

Application Information
VDD2 Power Supply Pins
Both VDD2 power supply inputs (pins 11 and 16) must be connected to the bus-side power supply. Pin 11 powers the bus side of the CAN I/O
circuitry, while pin 16 powers the bus-side isolation circuitry. For testing purposes, they are not internally connected, but the part will not operate
without both pins powered, and operation without both pins powered can cause damage.
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.
Input Configurations
The TxD input should not be left open as the state will be indeterminate. If connected to an open-drain or open collector output, a pull-up resistor
(typically 16 kΩ) should be connected from the input to VDD1.
The Mode Select (“S”) input has a nominal 150 kΩ internal pull-down resistor. It can be left open or set low for normal operation.
Dominant Mode Time-out and Failsafe Receiver Functions
CAN bus latch up is prevented by an integrated Dominant mode timeout func tion. 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.
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.
Replacing Non-Isolated Transceivers
The IL41050 is designed to re place common non-isolated CAN transceivers such as the Philips/NXP TJA1050 with minimal circuit changes.
Some notable differences:
• Some non-isolated CAN transceivers have internal TxD pull-up resistors, but the IL41050 TxD input should not be left open. If
connected to an open-drain or open collector output, a pull-up resistor (typically 16 kΩ) should be connected from the input to VDD1.
• Initialization behavior varies between CAN transceive rs. To ensure the desired power-up state, the IL41050 should be initialized with a
TxD pulse (low-to-high for recessive initialization), or shut down the transceiver in the desired power-up state (the “programmable
power-up feature”).
• Many non-isolated CAN transceivers have a VREF output. Such a reference is available on the IL41050 wide-body version.
The VREF Output
VREF is a reference voltage output used to drive bus threshold comparators in some legacy systems and is provided on the IL41050 wide-body
version. The output is half of the bus supply ±10% (i.e., 0. 45 VDD2 < VREF < 0.55 VDD2), and can drive up to 50 µA.
IsoRxD / IsoTxD Outputs
The IsoRxD and IsoTxD outputs are isolated versions of the RxD and TxD signals. These outputs are provided on the wide-body version for
troubleshooting, but normally no connections should be made to the pins.

The Isolation Advantage
Battery fire cause d by over or under charging of individual lithium ion ce lls 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 batteri es, 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 sour ce 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.
