Working Principle of ADM3101EARQZ

ADM3101EARQZ is a single-channel CAN transceiver that utilizes differential signaling for data transmission. It contains a CAN transceiver, a CAN controller, and a CAN protocol layer, integrated into one chip. This device is designed to work in a wide range of operating conditions and to operate efficiently within a given supply range of 5 V to 70 V. The CAN transceiver integrates a differential transmitter and receiver, supporting the CAN protocol based on ISO 11898-2.

The CAN controller implements the bus-level protocol based on the CAN standard. It monitors the activity on the bus, detects transmitted frames, and transmits frames when instructed by the protocol layer. The CAN protocol layer builds and checks frames in accordance with the CAN specifications, and is able to handle up to 32 message objects. The device also includes an EMC protection circuit that provides high speed and large capacitance to protect the transceiver against electro-static discharge.

The ADM3101EARQZ operates on either the high-speed (HS), low-speed (LS), or two-wire transceiver (TW) pins. By utilizing these pins, the device can communicate over a selectable transmission rate of up to 3 Mbps. This furthermore provides various features such as low power operation, improved ESD performance, immunity to EMI and complete bus fault diagnosis capabilities.

Overall, the ADM3101EARQZ provides a reliable, cost-effective solution for single-channel CAN communication systems. This device has become very popular in the field of industrial, automotive and home automation controls, due to its high performance, low power consumption and reliable operation.
