High Speed Low Power CAN
Transceiver
The NCV7341 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus and may be used in both 12 V and 24 V systems. The transceiver
provides differential transmit capability to the bus and differential
receive capability to the CAN controller.
Due to the wide common−mode voltage range of the receiver inputs,
the NCV7341 is able to reach outstanding levels of electromagnetic
susceptibility (EMS). Similarly, extremely low electromagnetic
emission (EME) is achieved by the excellent matching of the output
signals.
The NCV7341 is a new addition to the ON Semiconductor CAN
high−speed transceiver family and offers the following additional
features:
Features
• Ideal Passive Behavior when Supply Voltage is Removed
• Separate VIO Supply for Digital Interface Allowing Communication
to CAN Controllers and Microcontrollers with Different Supply
Levels
• Fully Compatible with the ISO 11898 Standard
• High Speed (up to 1 Mb)
• Very Low Electromagnetic Emission (EME)
• VSPLIT Voltage Source for Stabilizing the Recessive Bus Level if
Split Termination is Used (Further Improvement of EME)
• Differential Receiver with High Common−Mode Range for
Electromagnetic Immunity (EMI)
• Up to 110 Nodes can be Connected in Function of the Bus Topology
• Transmit Data (TxD) Dominant Time−out Function
• Bus Pins Protected Against Transients in Automotive Environments
• Bus Pins and Pin VSPLIT Short−Circuit Proof to Battery and Ground
• Thermally Protected
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• These are Pb−Free Devices*
Typical Applications
• Automotive
• Industrial Networks

1. In the sleep mode, all relevant parameters are guaranteed only for VBAT > 6 V. For VBAT between 5 V and 6 V, no power−on−reset will occur
and the functionality is also guaranteed, but some parameters might get slightly out of the specification − e.g. the wakeup detection
thresholds.
