As a CAN transceiver, it provides transmit and receive capability between the differential CAN bus and a CAN controller, with signaling rates up to 1 Mbps. Designed for operation in especially harsh environments, the device features cross-wire, overvoltage and loss of ground protection to ±36 V, with overtemperature protection and common-mode transient protection of ±100 V. This device operates over a –7-V to 12-V common-mode range with a maximum of 60 nodes on a bus.

Copyright © 2008, Texas Instruments Incorporated SN65HVD233-EP SLLS944 – NOVEMBER 2008............................................................................................................................................................................................ www.ti.com This device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. DESCRIPTION (CONTINUED) If the common-mode range is restricted to the ISO-11898 Standard range of –2 V to 7 V, up to 120 nodes may be connected on a bus. This transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications. The RS (pin 8) of the SN65HVD233 provides for three modes of operation: high-speed, slope control, or low-power standby mode. The high-speed mode of operation is selected by connecting RS directly to ground, allowing the driver output transistors to switch on and off as fast as possible with no limitation on the rise and fall slope. The rise and fall slope can be adjusted by connecting a resistor to ground at RS, since the slope is proportional to the pin's output current. Slope control is implemented with a resistor value of 10 kΩ to achieve a slew rate of ≈ 15 V/µs and a value of 100 kΩ to achieve ≈ 2.0 V/µs slew rate. For more information about slope control, refer to the application information section. The SN65HVD233 enters a low-current standby mode during which the driver is switched off and the receiver remains active if a high logic level is applied to RS. The local protocol controller reverses this low-current standby mode when it needs to transmit to the bus. A logic high on the loopback LBK (pin 5) of the SN65HVD233 places the bus output and bus input in a high-impedance state. The remaining circuit remains active and available for driver to receiver loopback, self-diagnostic node functions without disturbing the bus.

This forces the driver into a recessive state and redirects the data (D) input at pin 1 to the received-data output (R) at pin 4. This allows the host controller to input and read back a bit sequence to perform diagnostic routines without disturbing the CAN bus. A typical CAN bus application is displayed in Figure 25. If the LBK pin is not used it may be tied to ground (GND). However, it is pulled low internally (defaults to a low-level input) and may be left open if not in use.

Typical HVD233 Application ISO 11898 COMPLIANCE OF SN65HVD230 FAMILY OF 3.3-V CAN TRANSCEIVERS Introduction Many users value the low power consumption of operating their CAN transceivers from a 3.3 V supply. However, some are concerned about the interoperability with 5-V supplied transceivers on the same bus. This report analyzes this situation to address those concerns. Differential Signal CAN is a differential bus where complementary signals are sent over two wires and the voltage difference between the two wires defines the logical state of the bus. The differential CAN receiver monitors this voltage difference and outputs the bus state with a single-ended output signal. 18 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): SN65HVD233-EP SN65HVD233-EP www.ti.com............................................................................................................................................................................................ SLLS944 – NOVEMBER 2008 NOISE MARGIN 900 mV Threshold RECEIVER DETECTION WINDOW 75% SAMPLE POINT 500 mV Threshold NOISE MARGIN Figure 26. Typical SN65HVD230 Differential Output Voltage Waveform The CAN driver creates the difference voltage between CANH and CANL in the dominant state. The dominant differential output of the SN65HVD230 is greater than 1.5 V and less than 3 V across a 60-ohm load. The minimum required by ISO 11898 is 1.5 V and maximum is 3 V. These are the same limiting values for 5-V supplied CAN transceivers. The bus termination resistors drive the recessive bus state and not the CAN driver. A CAN receiver is required to output a recessive state with less than 500 mV and a dominant state with more than 900 mV difference voltage on its bus inputs. The CAN receiver must do this with common-mode input voltages from -2 V to 7 V. The SN65HVD230 family receivers meet these same input specifications as 5-V supplied receivers. Common-Mode Signal A common-mode signal is an average voltage of the two signal wires that the differential receiver rejects. The common-mode signal comes from the CAN driver, ground noise, and coupled bus noise. Obviously, the supply voltage of the CAN transceiver has nothing to do with noise. The SN65HVD230 family driver lowers the common-mode output in a dominant bit by a couple hundred millivolts from that of most 5-V drivers. While this does not fully comply with ISO 11898, this small variation in the driver common-mode output is rejected by differential receivers and does not effect data, signal noise margins or error rates. Interoperability of 3.3-V CAN in 5-V CAN Systems The 3.3-V supplied SN65HVD23x family of CAN transceivers are electrically interchangeable with 5-V CAN transceivers. The differential output is the same. The recessive common-mode output is the same. The dominant common-mode output voltage is a couple hundred millivolts lower than 5-V supplied drivers, while the receivers exhibit identical specifications as 5-V devices. Electrical interoperability does not assure interchangeability however. Most implementers of CAN buses recognize that ISO 11898 does not sufficiently specify the electrical layer and that strict standard compliance alone does not ensure interchangeability. This comes only with thorough equipment testing. BUS CABLE The ISO-11898 Standard specifies a maximum bus length of 40 m and maximum stub length of 0.3 m with a maximum of 30 nodes. However, with careful design, users can have longer cables, longer stub lengths, and many more nodes to a bus. A large number of nodes requires a transceiver with high input impedance such as the SN65HVD233.

Resistors equal to the characteristic impedance of the line terminate both ends of the cable to prevent signal reflections. Unterminated drop-lines (stubs) connecting nodes to the bus should be kept as short as possible to minimize signal reflections. SLOPE CONTROL The rise and fall slope of the SN65HVD233 driver output can be adjusted by connecting a resistor from Rs (pin 8) to ground (GND), or to a low-level input voltage as shown in Figure 27. The slope of the driver output signal is proportional to the pin's output current. This slope control is implemented with an external resistor value of 10 kΩ to achieve a ≈15 V/µs slew rate, and up to 100 kΩ to achieve a ≈2.0 V/µs slew rate as displayed in Figure 28.

Typical SN65HVD233 250-kbps Output Pulse Waveforms With Slope Control STANDBY If a high-level input (> 0.75 VCC) is applied to Rs (pin 8), the circuit enters a low-current, listen only standby mode during which the driver is switched off and the receiver remains active. The local controller can reverse this low-power standby mode when the rising edge of a dominant state (bus differential voltage >900 mV typical) occurs on the bus.
