The MAX33042E is a +5V CAN transceiver with integrated protection for industrial applications. This device has extended ±40V fault protection for equipment where overvoltage protection is required. It also incorporates high ±40kV ESD Human Body Model (HBM) protection and an input common-mode range (CMR) of ±25V, exceeding the ISO 11898-2 CAN standard of -2V to +7V. This makes it well suited for applications where there is moderate electrical noise that can influence the ground levels between two nodes or systems.

This device operates at a high-speed CAN data rate, allowing up to 4Mbps on short distance networks. Maximum speed on large networks may be limited by the number of nodes, the type of cabling used, stub length, and other factors. The MAX33042E includes a dominant timeout to prevent bus lockup caused by controller error or by a fault on the TXD input. When the TXD remains in the dominant state (low) for longer than tDOM, the driver is switched to the recessive state, releasing the bus and allowing other nodes to communicate.

The transceiver features a STBY pin for three modes of operation; standby mode for low current consumption, normal high-speed mode, or a slow slew rate mode when an external 26.1kΩ resistor is connected between ground and the STBY pin. A shutdown pin enables the device to further save power consumption where the transmitter and receiver are turned off.

The MAX33042E is available in 8-pin SOT23 and 8-pin SOIC packages. Both packages operate over the -40°C to +125°C temperature range.

Product Details

The MAX33042E shield is a fully assembled and tested printed circuit board (PCB) that demonstrates the functionality of the MAX33042E controller area network (CAN) transceiver with ±40V fault protection, extended ±25V common-mode input range, and ±40kV ESD human body model (HBM). The shield features a digital isolator, which is used as a level translator between the CAN transceiver and the controller interface.
