MAX33012E, CAN Transmission Error Detection and Reporting
MAX33072E: High CMR Enables Connectivity of Multiple Nodes


Today, automated manufacturing facilities tend to operate 24/7 to increase productivity and profitability. Consequently, the ability to quickly resolve equipment issues and restart the facility has become increasingly important.

Maxim Integrated announced on the 17th that it has released the MAX33012E, a CAN bus transceiver that increases uptime, and the MAX33072E, an RS-485 half-duplex transceiver that expands network size.

The MAX33012E detects, reports, and grades overvoltage, overcurrent, and transmission faults on CANH/CANL data lines. This allows operators to quickly detect anomalies and immediately reset the CAN network to online status. It also provides ±45kV electrostatic discharge (ESD) fault protection, enhancing ESD resistance for network data transmission.

The MAX33072E has a common-mode range (CMR) of ±40V for both input and output, enabling connections between multiple nodes and enhancing reliability. This product allows you to operate more machines over a wider area in noisy environments.
