MAX33012E integrates fault detection and reporting functions, greatly improving the reliability of CAN networks;MAX33072EExtend RS-485 network with the industry's highest common mode range

Beijing, China—September 17, 2020—Maxim Integrated Products, Inc. (NASDAQ: MXIM) announced the launchMAX33012EController Area Network (CAN) bus receiver andMAX33072E The RS-485 half-duplex transceiver helps designers to speed up the fault diagnosis of large networks and restore the normal communication of the system. It is ideal for industrial automation equipment that needs to maintain normal operation for a long time. These devices are designed to improve the uptime of industrial systems and are widely used in factory infrastructure networks. MAX33012E has the industry's most advanced fault detection and reporting functions; MAX33072E is used to connect different nodes distributed in a larger area, allowing higher ground potential differences between nodes, thereby greatly improving network reliability.

For many key industrial applications, such as asset management systems and communication fieldbus modules, reliable connections are the basic guarantee for optimizing production processes and improving system uptime.

MAX33012E: Overvoltage, overcurrent, and transmission errors on the CAN bus will cause production shutdowns and costly machines to idle. To overcome this challenge, MAX33012E can perform fault detection on data lines CANH and CANL, including overvoltage, overcurrent, and transmission faults, and report fault codes. The detection and reporting functions of MAX33012E can troubleshoot such failures at the fastest speed and re-establish link communication.

MAX33072E: Modern industrial and manufacturing systems require high common-mode voltage tolerance to support normal communication between different nodes. The common mode range (CMR) allowed by MAX33072E is 1.6 times higher than that of the nearest competitor (receiver). It is used to connect widely distributed nodes, thereby expanding the scale of the communication network and allowing more machines in a larger area. Work together inside, the link construction is simple and reliable. The MAX33072E's CMR is ±40V, which can reliably construct the connection and communication of industrial systems in noisy environments, allowing the ground potential difference between two nodes to be as high as -40V or +40V.

Main advantage

• Improve uptime: The CAN transceiver competition solution does not have both fault detection and reporting functions, resulting in system operators not knowing the source or specific details of the fault when diagnosing problems. MAX33012E relies on the industry's only fault detection, reporting, and overvoltage, overcurrent, and transmission error alignment capabilities to enable CAN networks to recover faster.
• Highest ESD protection: MAX33012E provides ±45kV electrostatic discharge (ESD) fault protection, which is 1.8 times higher than the closest competitor product, making the data transmission network can withstand higher ESD impact.
• Highest CMR The driver output and receiver input of MAX33072E have ultra-high CMR.

Evaluation

• "Automated production centers need to always operate around the clock to maximize productivity and return on investment." Colin Barnden, principal analyst at Semicast Research, said: "Quickly solving problems and quickly restoring production capacity after equipment shutdowns are urgent in any production environment. Features needed."
• "For industrial system designers, improving the normal working hours of industrial communications has a high priority." David Andeen, executive director of Maxim Integrated's core product division, said: "At any time, turning off equipment to find faults will cause huge losses to manufacturers. Of course. , Timely detection of faults can shorten repair time. Our new transceiver helps reduce machine idle time."
