AMIS41683CANN1G Application Field and Working Principle

The AMIS41683CANN1G is an integrated CAN transceiver designed specifically for applications requiring high-speed CAN node operation. It integrates a CAN transceiver with a CAN Controller Area Network (CAN) transceiver in a single package. The device is designed to transmit two copies of the CAN bit stream to two separate CAN bus systems, allowing them to be linked together. The CAN transceiver provides both direction control and dynamic biasing to detect and control the CAN bus signals, allowing for reliable low-power, high speed communication between the two CAN bus systems.

Application Field

The AMIS41683CANN1G is often used in applications where the highest possible data throughput and reliability are required. The device can be used in any application involving the control and/or communication of devices over a CAN bus system. It is often used in automotive applications such as powertrain, braking, suspension, body, and comfort systems. It is also used in applications such as industrial network systems, medical systems, security systems, and smart meter systems.

Working Principle

The AMIS41683CANN1G is based upon a dual-channel CAN bus transceiver design. The device consists of two logic sections: a CAN controller and a CAN transceiver circuit. The CAN controller provides arbitration, retransmission of messages, regulation of bus speed, and support of acknowledges and data frames. The CAN transceiver circuit provides fast, accurate transmission and reception of signals over the two-wire CAN bus system.

The CAN transceiver circuit consists of capacitors, resistors, and diodes to control the dynamic biasing of the CAN bus. At the receive end, the voltage at the CAN Bus Driver is compared to a reference voltage obtained from the CAN Transceiver Output. When these two voltages are equal, the CAN bus is driven with a steady state logic high. At the transmission end, the voltage is compared to the same reference voltage and a logic low is driven when the two readings are equal. This ensures that the CAN bus is driven at the correct frequency and is kept in a low power state.

The AMIS41683CANN1G is also able to detect errors in communication, such as noise and data corruption, by detecting an increase in the voltage of the CAN bus. When an error is detected, the device will temporarily stop transmitting and allow the bus controller to attempt to retransmit the data before resuming transmission.

The AMIS41683CANN1G is a unique integrated device which provides high speed data transmission and reliable operation for CAN bus systems. The device is compact, cost-effective, and reliable, making it an ideal choice for applications that require high-speed CAN node operation.
