The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard, High-K board, as specified in JESD51-7, in an environment described in JESD51-2a. The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8. The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDECstandard test exists, but a close description can be found in the ANSI SEMI standard G30-88. The junction-to-top characterization parameter, ΨJT, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining θJA, using a procedure described in JESD51-2a (sections 6 and 7). The junction-to-board characterization parameter, ΨJB estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining θJA, using a procedure described in JESD51-2a (sections 6 and 7). 7.6 Power Rating PARAMETER PD Average power dissipation TEST CONDITIONS POWER DISSIPATION UNIT VCC = 5 V, VIO = 5 V (if applicable), TJ = 27°C, RL = 60 Ω, S at 0 V, Input to TXD at 250 kHz, CL_RXD = 15 pF.

The DTO circuit timer starts on a falling edge on TXD. The DTO circuit disables the CAN bus driver if no rising edge is seen before the timeout period expires. This frees the bus for communication between other nodes on the network. The CAN driver is re-activated when a recessive signal is seen on the TXD terminal, thus clearing the TXD DTO condition. The receiver and RXD terminal still reflect activity on the CAN bus, and the bus terminals are biased to the recessive level during a TXD dominant timeout. TXD fault stuck dominant: example PCB failure or bad software TXD (driver) tTXD_DTO Fault is repaired & transmission capability restored Driver disabled freeing bus for other nodes %XV ZRXOG EH ³VWXFN GRPLQDQW´ EORFNLQJ FRPPXQLFDWLRQ IRU WKH whole network but TXD DTO prevents this and frees the bus for communication after the time tTXD_DTO. Normal CAN communication CAN Bus Signal tTXD_DTO Communication from other bus node(s) Communication from repaired node Communication from other bus node(s) Communication from repaired local node RXD (receiver) Communication from local node Figure 12. Example Timing Diagram for TXD DTO NOTE The minimum dominant TXD time allowed by the TXD DTO circuit limits the minimum possible transmitted data rate of the device. The CAN protocol allows a maximum of eleven successive dominant bits (on TXD) for the worst case, where five successive dominant bits are followed immediately by an error frame. This, along with the tTXD_DTO minimum, limits the minimum data rate. Calculate the minimum transmitted data rate by: Minimum Data Rate = 11 / tTXD_DTO. 9.3.2 Thermal Shutdown (TSD) If the junction temperature of the device exceeds the thermal shutdown threshold (TTSD), the device turns off the CAN driver circuits thus blocking the TXD-to-bus transmission path. The CAN bus terminals are biased to the recessive level during a thermal shutdown, and the receiver-to-RXD path remains operational. The shutdown condition is cleared when the junction temperature drops at least the thermal shutdown hysteresis temperature (TTSD_HYS) below the thermal shutdown temperature (TTSD) of the device.

Refer to Remote Wake Request via Wake Up Pattern (WUP) in Standby Mode NOTE After an undervoltage condition is cleared and the supplies have returned to valid levels, the device typically resumes normal operation within 50 µs. 9.3.4 Unpowered Device The device is designed to be 'ideal passive' or 'no load' to the CAN bus if it is unpowered. The bus terminals (CANH, CANL) have extremely low leakage currents when the device is unpowered to avoid loading down the bus. This is critical if some nodes of the network are unpowered while the rest of the of network remains in operation. The logic terminals also have extremely low leakage currents when the device is unpowered to avoid loading down other circuits that may remain powered. 9.3.5 Floating Terminals These devices have internal pull ups on critical terminals to place the device into known states if the terminals float. The TXD terminal is pulled up to VCC or VIO to force a recessive input level if the terminal floats. The terminal is also pulled up to force the device into low power Standby mode if the terminal floats. 9.3.6 CAN Bus Short Circuit Current Limiting The device has two protection features that limit the short circuit current when a CAN bus line is short-circuit fault condition: driver current limiting (both dominant and recessive states) and TXD dominant state time out to prevent permanent higher short circuit current of the dominant state during a system fault. During CAN communication the bus switches between dominant and recessive states, thus the short circuit current may be viewed either as the instantaneous current during each bus state or as an average current of the two states. For system current (power supply) and power considerations in the termination resistors and common-mode choke ratings, use the average short circuit current. Determine the ratio of dominant and recessive bits by the data in the CAN frame plus the following factors of the protocol and PHY that force either recessive or dominant at certain times: • Control fields with set bits • Bit stuffing 18 Submit Documentation Feedback Copyright © 2016–2019, Texas Instruments Incorporated Product Folder Links: TCAN1042-Q1 TCAN1042V-Q1 TCAN1042H-Q1 TCAN1042HV-Q1 TCAN1042G-Q1 TCAN1042GV-Q1 TCAN1042HG-Q1 TCAN1042HGV-Q1 TCAN1042-Q1, TCAN1042V-Q1, TCAN1042H-Q1 TCAN1042HV-Q1, TCAN1042G-Q1, TCAN1042GV-Q1 TCAN1042HG-Q1, TCAN1042HGV-Q1 www.ti.com SLLSES9C – FEBRUARY 2016 – REVISED MARCH 2019 • Interframe space • TXD dominant time out (fault case limiting) These ensure a minimum recessive amount of time on the bus even if the data field contains a high percentage of dominant bits. The short circuit current of the bus depends on the ratio of recessive to dominant bits and their respective short circuit currents. The average short circuit current may be calculated with the following formula: IOS(AVG) = %Transmit × [(%REC_Bits × IOS(SS)_REC) + (%DOM_Bits × IOS(SS)_DOM)] + [%Receive × IOS(SS)_REC] (1) Where: • IOS(AVG) is the average short circuit current • %Transmit is the percentage the node is transmitting CAN messages • %Receive is the percentage the node is receiving CAN messages • %REC_Bits is the percentage of recessive bits in the transmitted CAN messages • %DOM_Bits is the percentage of dominant bits in the transmitted CAN messages • IOS(SS)_REC is the recessive steady state short circuit current • IOS(SS)_DOM is the dominant steady state short circuit current NOTE Consider the short circuit current and possible fault cases of the network when sizing the power ratings of the termination resistance and other network components. 9.3.7 Digital Inputs and Outputs 9.3.7.1 5-V VCC Only Devices (Devices without the "V" Suffix): The 5-V VCC only devices are supplied by a single 5-V rail. The digital inputs have TTL input thresholds and are therefore 5 V and 3.3 V compatible. The RXD outputs on these devices are driven to the VCC rail for logic high output. Additionally, the TXD and STB pins are internally pulled up to VCC. The internal bias of the mode pins may only place the device into a known state if the terminals float, they may not be adequate for system-level biasing during transients or noisy enviroments. NOTE TXD pull up strength and CAN bit timing require special consideration when these devices are used with CAN controllers with an open-drain TXD output. An adequate external pull up resistor must be used to ensure that the CAN controller output of the micrcontroller maintains adequate bit timing to the TXD input. 9.3.7.2 5 V VCC with VIO I/O Level Shifting (Devices with the "V" Suffix): These devices use a 5 V VCC power supply for the CAN driver and high speed receiver blocks. These transceivers have a second power supply for I/O level-shifting (VIO). This supply is used to set the CMOS input thresholds of the TXD and pins and the RXD high level output voltage. Additionally, the internal pull ups on TXD and STB are pulled up to VIO.

Operating mode selection is made via the STB input terminal. Table 4.

A dominant bus state is when the bus is driven differentially, corresponding to a logic low on the TXD and RXD terminal. A recessive bus state is when the bus is biased to VCC / 2 via the high-resistance internal input resistors RIN of the receiver, corresponding to a logic high on the TXD and RXD terminals. Figure 13.

The CAN driver and receiver are fully operational and CAN communication is bi-directional. The driver translates a digital input on TXD to a differential output on CANH and CANL. The receiver translates the differential signal from CANH and CANL to a digital output on RXD. 9.4.3 Standby Mode Activate low power Standby mode by setting STB terminal high. In this mode the bus transmitter will not send data nor will the normal mode receiver accept data as the bus lines are biased to ground minimizing the system supply current. Only the low power receiver will be actively monitoring the bus for activity. RXD indicates a valid wake up event after a wake-up pattern (WUP) has been detected on the Bus. The low power receiver is powered using only the VIO pin. This allows VCC to be removed reducing power consumption further. The bus lines are biased to ground in Standby mode to minimize the required system supply current. The low power receiver is supplied by VIO and is capable of detecting CAN bus activity even if VIO is the only supply voltage available to the transceiver.

These devices use the multiple filtered dominant wake up pattern (WUP) from the ISO11898-2 (2016) to qualify bus activity. Once a valid WUP has been received the wake request will be indicated to the micrcontroller by a falling edge and low corresponding to a "filtered" dominant on the RXD output terminal. The WUP consists of a filtered dominant pulse, followed by a filtered recessive pulse, and finally by a second filtered dominant pulse. These filtered dominant, recessive, dominant pulses do not need to occur in immediate succession. There is no timeout that will occur between filtered bits of the WUP. Once a full WUP has been detected the device will continue to drive the RXD output low every time an additional filtered dominant signal is received from the bus. For a dominant or recessive signal to be considered "filtered", the bus must continually remain in that state for more than tWK_FILTER. Due to variability in the tWK_FILTER, the following three scenarios can exist: 1. Bus signals that last less than tWK_FILTER(MIN) will never be detected as part of a valid WUP 2. Bus signals that last more than tWK_FILTER(MIN) but less than tWK_FILTER(MAX) may be detected as part of a valid WUP 3. Bus signals that last more than tWK_FILTER(MAX) will always be detected as part of a valid WUP Once the first filtered dominant signal is received, the device is now waiting on a filtered recessive signal, other bus traffic will not reset the bus monitor. Once the filtered recessive signal is received, the monitor is now waiting on a second filtered dominant signal, and again other bus traffic will not reset the monitor. After reception of the full WUP, the device will transition to driving the RXD output pin low for the remainder of any dominant signal that remains on the bus for longer than tWK_FILTER.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information These CAN transceivers are typically used in applications with a host microprocessor or FPGA that includes the data link layer portion of the CAN protocol. Below are typical application configurations for both 5 V and 3.3 V microprocessor applications. The bus termination is shown for illustrative purposes. 10.2 Typical Applications Node n Node 1 Node 2 Node 3 MCU or DSP MCU or DSP MCU or DSP CAN Controller CAN Controller CAN Controller CAN Transceiver CAN Transceiver CAN Transceiver (with termination) MCU or DSP CAN Controller CAN Transceiver RTERM RTERM Figure 16. Typical CAN Bus Application 10.2.1 Design Requirements 10.2.1.1 Bus Loading, Length and Number of Nodes The ISO 11898-2 Standard specifies a maximum bus length of 40 m and maximum stub length of 0.3 m. 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 transceivers with high input impedance such as the TCAN1042 family of transceivers. Many CAN organizations and standards have scaled the use of CAN for applications outside the original ISO 11898-2. They have made system-level trade-offs for data rate, cable length, and parasitic loading of the bus. Examples of some of these specifications are ARINC825, CANopen, DeviceNet and NMEA2000. The TCAN1042 family is specified to meet the 1.5 V requirement with a 50Ω load, incorporating the worst case including parallel transceivers. The differential input resistance of the TCAN1042 family is a minimum of 30 kΩ. If 100 TCAN1042 family transceivers are in parallel on a bus, this is equivalent to a 300Ω differential load worst case. That transceiver load of 300 Ω in parallel with the 60Ω gives an equivalent loading of 50 Ω. Therefore, the TCAN1042 family theoretically supports up to 100 transceivers on a single bus segment. However, for CAN network design margin must be given for signal loss across the system and cabling, parasitic loadings, network imbalances, ground offsets and signal integrity thus a practical maximum number of nodes is typically much lower. Bus length may also be extended beyond the original ISO 11898 standard of 40 m by careful system design and datarate tradeoffs. For example CANopen network design guidelines allow the network to be up to 1 km with changes in the termination resistance, cabling, less than 64 nodes and significantly lowered data rate. 24 Submit Documentation Feedback Copyright © 2016–2019, Texas Instruments Incorporated Product Folder Links: TCAN1042-Q1 TCAN1042V-Q1 TCAN1042H-Q1 TCAN1042HV-Q1 TCAN1042G-Q1 TCAN1042GV-Q1 TCAN1042HG-Q1 TCAN1042HGV-Q1 TCAN1042-Q1, TCAN1042V-Q1, TCAN1042H-Q1 TCAN1042HV-Q1, TCAN1042G-Q1, TCAN1042GV-Q1 TCAN1042HG-Q1, TCAN1042HGV-Q1 www.ti.com SLLSES9C – FEBRUARY 2016 – REVISED MARCH 2019 Typical Applications (continued) This flexibility in CAN network design is one of the key strengths of the various extensions and additional standards that have been built on the original ISO 11898-2 CAN standard. In using this flexibility comes the responsibility of good network design and balancing these tradeoffs. 10.2.2 Detailed Design Procedures 10.2.2.1 CAN Termination The ISO 11898 standard specifies the interconnect to be a twisted pair cable (shielded or unshielded) with 120-Ω characteristic impedance (ZO). Resistors equal to the characteristic impedance of the line should be used to 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. The termination may be on the cable or in a node, but if nodes may be removed from the bus, the termination must be carefully placed so that two terminations always exist on the network. Termination may be a single 120-Ω resistor at the end of the bus, either on the cable or in a terminating node. If filtering and stabilization of the common mode voltage of the bus is desired, then split termination may be used. (See Figure 17). Split termination improves the electromagnetic emissions behavior of the network by eliminating fluctuations in the bus common-mode voltages at the start and end of message transmissions.

Some devices have an output level shifting supply input, VIO, designed for a range between 3.0 V and 5.5 V. Both supply inputs must be well regulated. A bulk capacitance, typically 4.7 μF, should be placed near the CAN transceiver's main VCC supply output, and in addition a bypass capacitor, typically 0.1 μF, should be placed as close to the device's VCC and VIO supply terminals. This helps to reduce supply voltaeg ripple present on the outputs of the switched-mode power supplies and also helps to compensate for the resistance and inductance of the PCB power planes and traces. 12 Layout Robust and reliable bus node design often requires the use of external transient protection device in order to protect against EFT and surge transients that may occur in industrial enviroments. Because ESD and transients have a wide frequency bandwidth from approximately 3 MHz to 3 GHz, high-frequency layout techniques must be applied during PCB design. The family comes with high on-chip IEC ESD protection, but if higher levels of system level immunity are desired external TVS diodes can be used. TVS diodes and bus filtering capacitors should be placed as close to the on-board connectors as possible to prevent noisy transient events from propagating further into the PCB and system. 28 Submit Documentation Feedback Copyright © 2016–2019, Texas Instruments Incorporated Product Folder Links: TCAN1042-Q1 TCAN1042V-Q1 TCAN1042H-Q1 TCAN1042HV-Q1 TCAN1042G-Q1 TCAN1042GV-Q1 TCAN1042HG-Q1 TCAN1042HGV-Q1 TCAN1042-Q1, TCAN1042V-Q1, TCAN1042H-Q1 TCAN1042HV-Q1, TCAN1042G-Q1, TCAN1042GV-Q1 TCAN1042HG-Q1, TCAN1042HGV-Q1 www.ti.com SLLSES9C – FEBRUARY 2016 – REVISED MARCH 2019 12.1 Layout Guidelines • • • Place the protection and filtering circuitry as close to the bus connector, J1, to prevent transients, ESD and noise from propagating onto the board. In this layout example a transient voltage suppression (TVS) device, D1, has been used for added protection. The production solution can be either bi-directional TVS diode or varistor with ratings matching the application requirements. This example also shows optional bus filter capacitors C4 and C5. Additionally (not shown) a series common mode choke (CMC) can be placed on the CANH and CANL lines between the transceiver U1 and connector J1. Design the bus protection components in the direction of the signal path. Do not force the transient current to divert from the signal path to reach the protection device. Use supply (VCC) and ground planes to provide low inductance. NOTE High-frequency currents follows the path of least impedance and not the path of least resistance. • • • • • • • Use at least two vias for supply (VCC) and ground connections of bypass capacitors and protection devices to minimize trace and via inductance. Bypass and bulk capacitors should be placed as close as possible to the supply terminals of transceiver, examples are C1, C2 on the VCC supply and C6 and C7 on the VIO supply. Bus termination: this layout example shows split termination. This is where the termination is split into two resistors, R6 and R7, with the center or split tap of the termination connected to ground via capacitor C3. Split termination provides common mode filtering for the bus. When bus termination is placed on the board instead of directly on the bus, additional care must be taken to ensure the terminating node is not removed from the bus thus also removing the termination. See the application section for information on power ratings needed for the termination resistor(s). To limit current of digital lines, serial resistors may be used. Examples are R2, R3, and R4. These are not required. Terminal 1: R1 is shown optionally for the TXD input of the device. If an open drain host processor is used, this is mandatory to ensure the bit timing into the device is met. Terminal 5: For "V" variants of the family, bypass capacitors should be placed as close to the pin as possible (example C6 and C7). For device options without VIO I/O level shifting, this pin is not internally connected and can be left floating or tied to any existing net, for example a split pin connection. Terminal 8: is shown assuming the mode terminal, STB, will be used. If the device will only be used in normal mode, R4 is not needed and R5 could be used for the pull down resistor to GND. 12.2 Layout Example VCC or VIO R5 R1 R2 TXD R6 7 4 5 R7 C5 6 C6 C7 3 J1 C3 GND D1 U1 U1 C2 C1 R3 C4 2 VCC GND 8 1 GND RXD R4 STB GND VIO GND Copyright © 2016–2019, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TCAN1042-Q1 TCAN1042V-Q1 TCAN1042H-Q1 TCAN1042HV-Q1 TCAN1042G-Q1 TCAN1042GV-Q1 TCAN1042HG-Q1 TCAN1042HGV-Q1 29 TCAN1042-Q1, TCAN1042V-Q1, TCAN1042H-Q1 TCAN1042HV-Q1, TCAN1042G-Q1, TCAN1042GV-Q1 TCAN1042HG-Q1, TCAN1042HGV-Q1 SLLSES9C – FEBRUARY 2016 – REVISED MARCH 2019 www.ti.com 13 Device and Documentation Support 13.1 Related Links The table below lists quick access links.
