MAX33053E/MAX33054E +3.3V, 2Mbps CAN Transceiver with ±65V Fault Protection, ±25V CMR, and ±25kV ESD General Description The MAX33053E and MAX33054E are +3.3V CAN (Control Area Network) transceivers with integrated protection for industrial applications. These devices have extended ±65V fault protection for equipment where overvoltage protection is required. It also incorporates high ±25kV ESD HBM and an input common mode range (CMR) of ±25V, exceeding the ISO 11898 specification of -2V to +7V. This makes these parts well-suited for applications that are in electrically noisy environments where the ground planes are shifting relative to each other. This family features a variety of options to address common CAN application requirements; logic-level supply input VL for interfacing with 1.62V to 3.6V logic, lowcurrent standby mode, silent-mode to disable the transmitter, and a slow slew rate to minimize EMI. These devices operate at a high-speed CAN data rate, allowing up to 2Mbps on small networks. Maximum speed on large networks may be limited by the number of nodes in a network, the type of cabling used, stub length, and other factors. These transceivers 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. The MAX33053E features an S pin where it enables and disables the transmitter for applications where you need the transceiver to receive only. The MAX33054E features a STBY pin for 3 modes of operation; standby mode for low-current consumption, normal high-speed mode, or a slow slew rate mode when an external 26.1kΩ is connected between ground and STBY pin. The MAX33053E and MAX33054E are available in a standard 8-pin SOIC package and operate over the -40°C to +125°C temperature range.

These devices provide a link between the CAN protocol controller and the physical wires of the bus lines in a control area network (CAN). They can be used for DeviceNet™ applications as well. The MAX33053E and MAX33054E protect the transmitter output stage against a short-circuit to a positive or negative voltage by limiting the driver current. Thermal shutdown further protects the devices from excessive temperatures that may result from a short or high ambient temperature. The transmitter returns to normal operation once the temperature is lowered below the threshold. The two CAN transceivers are fault-protected up to ±65V, making it suitable for applications where overvoltage protection is required. These devices are rated up to a high ±25kV ESD of HBM (Human Body Model), suitable for protection during the manufacturing process, and even in the field where there is human interface for installation and maintenance. In addition, a common mode voltage of ±25V enables communication in noisy environments where there are ground plane differences between different systems due to close proximity of heavy equipment machinery or operation from different transformers. The devices' dominant timeout prevents the bus from being blocked by a hung-up microcontroller, and the outputs CANH and CANL are short-circuit, current-limited, and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs in a high-impedance state. Transmitter-Dominant Timeout Both devices can operate up to 2Mbps, while the MAX33054E has an option to slow the slew rate to 8V/s to minimize EMI, enabling the use of unshielded twisted or parallel cable. The MAX33054E features a standby mode where it shuts off the transmitter and reduces the current to 45μA, typical. These CAN transceivers have a VL pin where an integrated logic level translator enable it to interface with low-voltage microcontrollers down to 1.8V ±10%. ±65V Fault Protection These devices feature ±65V of fault protection. CANH and CANL data lines are capable of withstanding a short from -65V to +65V. This extended overvoltage range makes it suitable for applications where accidental shorts to power supply lines are possible due to human intervention. Transmitter The transmitter converts a single-ended input signal (TXD) from the local CAN controller to differential outputs for the bus lines CANH and CANL. The truth table for the transmitter and receiver is provided in Table 1. The devices feature a transmitter dominant timeout (tDOM) that prevents erroneous CAN controllers from clamping the bus to a dominant level by maintaining a continuous low TXD signal. When TXD remains in the dominant state (low) for greater than 2.5ms typical tDOM, the transmitter is disabled, releasing the bus to a recessive state (Figure 4). After a dominant timeout fault, the transmitter is re-enabled when receiving a rising edge at TXD. The transmitter dominant timeout limits the minimum possible data rate to 9kbps for standard CAN protocol. Receiver The receiver reads the differential input from the bus line CANH and CANL and transfers this data as a singleended output RXD to the CAN controller. It consists of a comparator that senses the difference VDIFF = (CANHCANL), with respect to an internal threshold of 0.7V. If VDIFF > 0.9V, a logic-low is present on RXD. If VDIFF < 0.5V, a logic-high is present. The CANH and CANL common-mode range is ±25V. RXD is a logic-high when CANH and CANL are shorted or terminated and undriven. Standby Mode (MAX33054E) Drive STBY pin high for standby mode, which switches the transmitter off and the receiver to a low current and low-speed state. The supply current is reduced during standby mode. The bus line is monitored by a low differential comparator to detect and recognize a wakeup event on the bus line. Once the comparator detects a dominant bus level greater than 2.5μs typical tWAKE, RXD pulls low. Drive the STBY low for normal operation. Slow Slew Rate (MAX33054E) Connect a 26.1kΩ resistor between ground and the STBY pin. The STBY pin voltage should be between 0.1V to 0.6V to remain in slow slew rate. This will change the MAX33054E with a slow slew rate of 8V/μs for rising edge compared with normal mode at 180V/μs. For falling edge, the slow slew rate is 20V/μs compared with normal mode at 140V/μs.

This disables the transmitter regardless of the voltage level at TXD. However, RXD is still active and monitors activity on the bus line. Logic Compatibility A separate input VL allows the MAX33053E and MAX33054E to communicate with logic systems down to 1.62V while operating up to a +3.6V supply. This provides a reduced input voltage threshold to the TXD, STBY, and S inputs, and provides a logic-high output at RXD compatible with the microcontroller's supply rail. The logic compatibility eliminates an external logic level translator and longer propagation delay due to level shifting. Connect VL to VDD to operate with +3.3V logic systems. Applications Information Reduced EMI and Reflections In multidrop CAN applications, it is important to maintain a single linear bus of uniform impedance that is properly terminated at each end. A star, ring, or tree configuration should never be used. Any deviation from the end-to-end wiring scheme creates a stub. High-speed data edges on a stub can create reflections back down to the bus. These reflections can cause data errors by eroding the noise margin of the system. Although stubs are unavoidable in a multidrop system, care should be taken to keep these stubs as short as possible, especially when operating with high data rates. Table 1.
