Introduction

The MAX13481EETE+ is a versatile, low-power, high-performance isolated CAN transceiver featuring integrated power- and thermal-management features. This transceiver is targeted at automotive applications, including collision avoidance (CA), train safety systems, and advanced driver assistance systems (ADAS).

Application Field

The main application field of MAX13481EETE+ is characterized by being used as an isolated transceiver for automotive networks using CAN bus protocols. It enables communication between the modules.

A wide range of vehicles use the MAX13481EETE+ for collisions avoidance, advanced driver assistance systems and train protection. It offers versatility, low-power capability and an integrated power- and thermal-management feature. In addition, it supports AHB (Advanced High-Speed Bus), HIS (High-Speed Interconnect System), and USB (Universal Serial Bus).

The main application field of MAX13481EETE+ also includes collision avoidance (CA) systems, train safety systems, and advanced driver assistance systems (ADAS). It enables communication within the data bus and between the components on-board. This isolates the CAN bus from external signals, avoiding interference and reducing EMI (Electromagnetic Interference).

Working Principle

The working principle of the MAX13481EETE+ transceiver is based on the CAN physical layer protocol specification 2.0 A/B. The CAN physical layer creates a level of communication between two connected CAN nodes. This communication is accomplished through voltage levels, applied and sensed on the data bus. A logical zero is interpreted as a (low) voltage less than or equal to 0. 0 V, while any other voltage is interpreted as a “logical one”.

The MAX13481EETE+ transceiver features a wide common-mode voltage range of -28 V to +28 V, high-speed operation of up to 1 Mbps, and performs ESD protection of up to ±15 kV. The transceiver also features a low-power shutdown mode, a low-voltage detect (LVD) feature, and fault tolerance.

The transceiver operates in both un-powered and powered modes. In unpowered modes, the transceiver simply reads the input signal from the CAN bus and converts it into an electrical output that can be read by the connected nodes. In powered mode, the transceiver is able to actively transmit signals to the bus. The transceiver senses the voltage levels at the signal lines and is able to convert its electrical signals into the data to be sent to the bus.

The MAX13481EETE+ transceiver is a power-saving, high-performance isolated CAN transceiver solution. It provides high-speed communications between optional components, improved protection from noise and static, and reduced EMI emissions.

Conclusion

The MAX13481EETE+ is a versatile, low-power, high-performance isolated CAN transceiver featuring integrated power- and thermal-management features. It is a great solution for automotive applications, such as collisions avoidance (CA), train safety systems, and advanced driver assistance systems (ADAS). The transceiver operates using the CAN physical layer protocol specification 2.0 A/B, allowing communication between optional components while providing protection from noise and static. Additionally, the low-power shutdown mode, low-voltage detect (LVD) feature, and built-in fault tolerance make the transceiver a great choice for these automotive applications.
