MAX33042E +5V, 4Mbps CAN Transceiver with 40V Fault Protection, 25V CMR, and 40kV ESD in 8-Pin SOT23 General Description Benefits and Features The MAX33042E is a +5V CAN transceiver with Integrated Protection Increases Robustness integrated protection for industrial applications. This Increased Protection on CANH and CANL device has extended 40V fault protection for equipment - 40V Fault Tolerant where overvoltage protection is required. It also - 40kV ESD HBM Protection incorporates high 40kV ESD Human Body Model - 12kV Contact and 15kV Air-Gap ESD (ISO (HBM) protection and an input common-mode range 10605, IEC 61000-4-2) Protection (CMR) of 25V, exceeding the ISO 11898-2 CAN - 25V Extended Common-Mode Input Range standard of -2V to +7V. This makes it well suited for (CMR) applications where there is moderate electrical noise - Short-Circuit Protection that can influence the ground levels between two nodes Transmitter-Dominant Timeout Prevents Lockup or systems. Thermal Shutdown This device operates at a high-speed CAN data rate, Provides Flexible Design Options allowing up to 4Mbps on short distance networks. Slow Slew Rate to Minimize EMI Maximum speed on large networks may be limited by Low-Current Standby Mode the number of nodes, the type of cabling used, stub Shutdown Pin to Save Power length, and other factors. The MAX33042E includes a Small Package Option to Save PCB Area dominant timeout to prevent bus lockup caused by 8-Pin SOT23 controller error or by a fault on the TXD input. When the High-Speed Operation of up to 4Mbps TXD remains in the dominant state (low) for longer than Operating Temperature Range of -40C to +125C t , the driver is switched to the recessive state, DOM releasing the bus and allowing other nodes to Ordering Information appears at end of data sheet. 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 26.1k 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 -40C to +125C temperature range. Applications Industrial Equipment Instrumentation Motor Control Building Automation 19-100965 Rev 1 12/21 2021 Analog Devices, Inc.
