MAX33012E improves CAN reliability through integrated fault detection and reporting; MAX33072E expands RS-485 networks with industry’s highest common mode range
Designers requiring longer uptime for industrial automation applications can accelerate troubleshooting and communicate across larger networks with the MAX33012E controller area network (CAN) bus transceiver and the MAX33072E RS-485 half-duplex transceiver from Maxim Integrated Products, Inc. These devices are designed to increase industrial system uptime for factory-floor networks. The MAX33012E features the industry’s most advanced fault detection and reporting, while the MAX33072E provides the ability to connect the broadest range of disparate nodes, increasing reliability by enabling the connection of nodes with large ground differences.
Reliable connectivity is essential to optimizing operation and improving system uptime in manufacturing for many critical industrial applications, such as asset management systems and communication fieldbus modules.
MAX33012E: Overvoltage, overcurrent and transmission error faults in CAN will shut down production and idle expensive machinery. To overcome this challenge, the MAX33012E features fault detection on data lines CANH and CANL for overvoltage, overcurrent and transmission failure, as well as fault code reporting. The MAX33012E’s detection and reporting enable the fastest troubleshooting of these faults so vital links can be immediately re-established.
MAX33072E: Modern industrial and manufacturing systems require high common mode voltage tolerance to communicate between disparate systems. The common mode range (CMR) of the MAX33072E is 1.6x greater than that of the closest competitor (receiver only). With the ability to connect the broadest range of disparate nodes, it expands communication network size to allow more machines to operate across larger areas, with simple and reliable links. The MAX33072E CMR of ±40V enables industrial systems to connect and communicate in environments of greater electrical noise, up to where a difference of either -40V or +40V between two nodes is present.
