Product Details
The MAX33040E/MAX33041E are +3.3V control area network (CAN) transceivers with integrated protection for industrial applications. These devices have extended ±40V fault protection on CANH and CANL for equipment where overvoltage protection is required. They also incorporate high ±40kV ESD HBM and an input common-mode range (CMR) of ±25V on CANH and CANL, exceeding the ISO 11898-2 CAN standard of -2V to +7V. This makes these parts well suited for applications where there is moderate electrical noise that can influence the ground levels between two nodes or systems. These parts feature a shutdown pin and a multifunction standby pin.
These devices operate at a high-speed CAN data rate, allowing up to 5Mbps 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 MAX33040E/MAX33041E include a dominant timeout to prevent bus lockup caused by controller error or by a fault on the TXD input. When 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. These devices feature 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 39.2kΩ resistor is connected between ground and STBY pin.
The MAX33040E is available in an 8-bump WLP and 8-pin SOT23, while the MAX33041E is available in an 8-pin SOIC package. Both parts operate over the -40°C to +125°C temperature range.
