±80V Fault-Protected Can Transceiver with Autobaud The MAX13051 ±80V fault-protected CAN transceiver with autobaud
19-3500; Rev 0; 11/04 ±80V Fault-Protected Can Transceiver with Autobaud The MAX13051 MAX13051 ±80V fault-protected CAN transceiver with autobaud is ideal for device net and other industrial network applications where overvoltage protection is required. The MAX13051 MAX13051 provides a link between the CAN protocol controller and the physical wires of the bus lines in a control area network (CAN). The MAX13051 MAX13051 features three different modes of operation: high speed, slope control, and standby. Highspeed mode allows data rates up to 1Mbps. The slope-control mode can be used to program the slew rate of the transmitter for data rates of up to 500kbps, reducing the effects of EMI and allowing the use of unshielded-twisted or parallel cable. In standby mode, the transmitter shuts off and a low-power receiver monitors the bus, waiting for a wake-up signal. The MAX13051 MAX13051 provides a transmitter data (TXD) dominant timeout function that prevents erroneous CAN controllers from clamping the bus to a dominant level if the TXD input is held low for greater than 1ms. The MAX13051 MAX13051 also provides an autobaud feature allowing the microcontroller to compute the incoming baud rate without destroying CAN protocol communication. The MAX13051 MAX13051 input common-mode range is greater than ±12V, exceeding the ISO 11898 specification of -2V to +7V, and features ±6kV Human Body Model protection, making these devices ideal for harsh environments. The MAX13051 MAX13051 is available in an 8-pin SO package and is specified from the -40°C to +85°C and -40°C to +125°C temperature ranges.

MAX13051 MAX13051 Functional Diagram Detail Description ±80V Fault Tolerant The MAX13051 MAX13051 features ±80V fault protection. This extended voltage range of CANH and CANL allows communication in high-voltage systems up to 80V. Operating Modes High-Speed Mode The MAX13051 MAX13051 can achieve transmission rates of up to 1Mbps when operating in high-speed mode. To operate in high-speed mode, short RS to ground. Slope-Control Mode Connect a resistor from RS to ground to select slopecontrol mode (Table 1). In slope-control mode, CANH and CANL slew rates are controlled by the resistor, (16k RRS 200k), connected between RS and GND. Controlling the rise and fall slopes reduces highfrequency EMI and allows the use of an unshieldedtwisted pair or a parallel pair of wires as bus lines. The slew rate can be approximated using the formula below: 8 SR (V / µs) 250 RRS where, SR is the desired slew rate and RRS is in k. Standby Mode In standby mode (RS = high), the transmitter is switched off and the receiver is switched to a low-current/low-speed state. The supply current reduces to 15µA to detect and recognize a wake-up event on the bus line. During standby mode, the bus line is monitored with a low-differential comparator. Once the comparator detects a dominant bus level greater than tWAKE, RXD pulls low. Autobaud Mode The MAX13051 MAX13051 logic-controlled autobaud input allows a microcontroller to compute the incoming baud rate without destroying CAN protocol communication. When operating in autobaud mode, TXD is looped back to RXD without applying a differential signal at CANH and CANL.

TXD TRANSMITTER INPUT RXD RECEIVER OUTPUT AUTOBAUD TXD CANH - CANL RXD Figure 4. MAX13051 MAX13051 Autobaud Timing Diagram Transmitter The transmitter converts a single-ended input (TXD) from the CAN controller to differential outputs for the bus lines (CANH, CANL). The truth table for the transmitter and receiver is given in Table 2. TXD Dominant Timeout The MAX13051 MAX13051 provides a transmitter-dominant timeout that prevents erroneous CAN controllers from clamping the bus to a dominant level by maintaining a continuous low TXD signal. When the TXD remains in the dominant state for greater than 1ms (max), the transmitter becomes disabled, driving the bus line to a recessive state (Figure 5). After a dominant timeout fault, the MAX13051 MAX13051's transmitter becomes enabled upon detecting a rising edge at TXD. Receiver The receiver reads differential inputs from the bus lines (CANH, CANL) and transfers this data as a singleended output (RXD) to the CAN controller. It consists of a comparator that senses the difference, V DIFF = (CANH - CANL), with respect to an internal threshold of 0.7V. If this difference is positive, (VDIFF > 0.9V), a logic-low is present at RXD. If negative, (VDIFF < 0.5V), a logic-high is present. The receiver always echoes the CAN bus data when not operating in autobaud mode. _ 9 MAX13051 MAX13051 ±80V Fault-Protected Can Transceiver with Autobaud junction temperature drops below the thermal-shutdown hysteresis, and upon the MAX13051 MAX13051 detecting a rising edge at TXD. tDOM TRANSMITTER ENABLED Applications Information TXD Reduced EMI and Reflections TRANSMITTER DISABLED VCANH - VCANL Figure 5. Transmitter-Dominant Timeout Timing Diagram The CANH and CANL common-mode range is ±12V exceeding the ISO 11898 specification at -2V to +7V. RXD is logic-high when CANH and CANL are shorted or undriven. Driver Output Protection The MAX13051 MAX13051 current-limiting feature protects the transmitter output stage against a short circuit to a positive and negative battery voltage. Although the power dissipation increases during this fault condition, currentlimit protection prevents destruction of the transmitter output stage. Upon removal of a short, the MAX13051 MAX13051 resumes normal operation. Thermal Shutdown If the junction temperature exceeds +165°C, the device is switched off. The hysteresis is approximately 13°C, disabling thermal shutdown once the temperature drops below 152°C. In thermal shutdown, CANH and CANL go recessive. After a thermal-shutdown event, the MAX13051 MAX13051 resumes normal operation when the MAX13051 MAX13051 RL = 120 In slope-control mode, the CANH and CANL outputs are slew-rate limited, minimizing high-frequency EMI, and reducing reflections caused by improperly terminated cables. In multidrop CAN applications, it is important to maintain a direct point-to-point wiring scheme. A single pair of wires should connect each element of the CAN bus, and the two ends of the bus should be terminated with 120 resistors, see Figure 6. A star configuration should never be used. Any deviation from the point-to-point wiring scheme creates a stub. The high-speed edge of the CAN data on a stub can create reflections back down 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 small as possible, especially in high-speed mode. In slope-control mode, the requirements are not as rigorous, but stub length should still be minimized. Layout Consideration CANH and CANL are differential signals and steps should be taken to insure equivalent parasitic capacitance. Place the resistor at RS as close as possible to the MAX13051 MAX13051 to minimize any possible noise coupling at the input.

Human Body Model Current Waveform ESD Test Conditions The MAX13051 MAX13051 requires no special layout considerations beyond common practices. Bypass VCC to GND with a 0.1µF ceramic capacitor mounted closely to the IC with short lead lengths and wide trace widths. ESD performance depends on a number of conditions. Contact Maxim for a reliability report that documents test setup, methodology, and results. ±6kV ESD Protection Figure 7 shows the Human Body Model, and Figure 8 shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the device through a 1.5k resistor. ESD protection structures are incorporated on all inputs to protect against ESD encountered during handling and assembly. CANH and CANL inputs have extra protection to protect against static electricity found in normal operation. Maxim's engineers have developed state-of-the-art structures to protect these pins (CANH, CANL) against ±6kV ESD without damage. ESD protection can be tested in several ways. The CANH and CANL inputs are characterized for protection to ±6kV using the Human Body Model.
