Description
The IL41050TA is a galvanically isolated, CAN (Controller Area
N
etwork) t
r
ansceiver, designed as the interface between the CAN
protocol controller and the physical bus.
Quiescent and dynamic supply current is significantly lower than
N
VE’s higher speed CAN (Controller Area Network) transceivers.
The IL41050 family 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.
A unique ceramic/polymer composite barrier provides excellent
isolation and virtually unlimited barrier life.
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, IL41050TA
transceivers have transmit data dominant time-out, bus pin transient
protection, a rugged Charged Device Model ESD rating, thermal
shutdown protection, and short-circuit protection. Unique edge-
triggered inputs improve noise performance.

Bus-Side 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.
Maintaining Creepage
Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have unique creepage
specifications. Standard pad libraries often extend under the package, compromising creepage and clearance. Similarly, ground planes, if used,
should be spaced to avoid compromising clearance. Package drawings and recommended pad layouts are included in this datasheet.
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 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 when 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 the 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 replace 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 transceivers. 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 for troubleshooting on the
narrow-body version, but normally no connections should be made to the pins.
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.

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 below:
