This serial data link network is intended for use in applications where high data rate is not required and a lower data rate can achieve cost reductions in both the physical media components and in the microprocessor and/or dedicated logic devices which use the network. The network shall be able to operate in either the normal data rate mode or a high speed data download mode for assembly line and service data transfer operations. The high speed mode is only intended to be operational when the bus is attached to an off-board service node. This node shall provide temporary bus electrical loads which facilitate higher speed operation. Such temporary loads shall be removed when not performing download operations. The bit rate for normal communications is typically 33 kbit/s, for high speed transmissions like described above a typical bit rate of 83 kbit/s is recommended. The TH8055 is designed in accordance to the Single Wire CAN Physical Layer Specification GMW3089 V1.26 and supports many additional features like undervoltage lockout, timeout for faulty blocked input signals, output blanking time in case of bus ringing and a very low sleep mode current.

Functional Description 2.1 TxD Input Pin TxD Polarity TxD = logic 1 (or floating) on this pin produce an undriven or recessive bus state (low bus voltage) TxD = logic 0 on this pin produce either a bus normal or a bus high voltage dominant state depending on the transceiver mode state (high bus voltage) If the TxD pin is driven to a logic low state while the sleep mode (Mode0=0 and Mode1=0) is activated, the transceiver not drive the CANH pin to the dominant state. The transceiver provides an internal pull up current on the TxD pin which will cause the transmitter to default to the bus recessive state when TxD is not driven. TxD input signals are standard CMOS logic levels. Timeout Feature In case of a faulty blocked dominant TxD input signal the CANH output is switched off automatically after the specified TxD timeout reaction time to prevent a dominant bus. The transmission is continued by next TxD L to H transition without delay. 2.2 Mode 0 and Mode 1 pins The transceiver provides a weak internal pull down current on each of these pins which causes the transceiver to default to sleep mode when they are not driven. The mode input signals are standard CMOS logic level. M0 M1 Mode L L Sleep mode H L High speed mode L H Wake up H H Normal mode Sleep Mode Transceiver is in low power state, waiting for wake up via high voltage signal or by mode pins change to any state other than 0,0. In this state, the CANH pin is not in the dominant state regardless of the state of the TxD pin. High Speed Mode This mode allows high speed download with bitrates up to 100Kbit/s. The output waveshaping circuit is disabled in this mode. Bus transmitter drive circuits for those nodes which are required to communicate in high speed mode are able to drive reduced bus resistance in this mode (see Table Static Characteristics). High speed communications shall utilize the normal mode signal voltage levels as specified in Static Characteristics. TH8055 - Datasheet 3901008055 Page 4 of 20 May 2004 Rev 005 TH8055 Single Wire CAN Transceiver Wake Up Mode This bus includes a selective node awake capability, which allows normal communication to take place among some nodes while leaving the other nodes in an undisturbed sleep state. This is accomplished by controlling the signal voltages such that all nodes must wake up when they receive a higher voltage message signal waveform. The communication system communicates to the nodes information as to which nodes are to stay operational (awake) and which nodes are to put themselves into a non communicating low power “sleep” state. Communication at the lower, normal voltage levels shall not disturb the sleeping nodes. Normal mode Transmission bit rate in normal communication is 33 Kbits/s. In normal transmission mode the TH8055 supports controlled waveform rise and overshoot times. Waveform trailing edge control is required to assure that high frequency components are minimized at the beginning of the downward voltage slope. The remaining fall time occurs after the bus is inactive with drivers off and is determined by the RC time constant of the total bus load. 2.3 RxD Output pin RxD polarity RxD = logic 1 on this pin indicates a bus recessive state (low bus voltage) RxD = logic 0 on this pin indicates a bus normal or high voltage bus dominant state RxD in Sleep Mode RxD do not pass signals to the micro processor while in sleep mode until a valid wake up bus voltage level is received or the Mode 0,1 pins are not 0,0 respectively. When the valid wake up bus voltage signal awakens the transceiver, the RxD pin signalised an interrupt (logic 0). However, if the Mode 0 & 1 pins are at logic 0, the transceiver returns to the sleep condition when the wake up bus voltage signal is not present. When not in sleep mode all valid bus signals will be sent out on the RxD pin. RxD will be placed in the undriven or off state when in sleep mode. RxD Typical Load Resistance: 2.7 kOhm Capacitance: < 25 pF 2.4 Bus LOAD pin Resistor ground with internal open-on-loss-of-ground protection When the ECU experiences a loss of ground condition, this pin is switched to a high impedance state. The ground connection through this pin is not interrupted in any transceiver operating mode including the sleep mode. The ground connection only is interrupted when there is a valid loss of ground condition. This pin provides the bus load resistor with a path to ground which contributes less than 0.1 volts to the bus offset voltage when sinking the maximum current through one unit load resistor. The transceiver’s maximum bus leakage current contribution to VOL from the LOAD pin when in a loss of ground state is 50uA over all operating temperatures and 3.5 < VBAT < 18 volts . TH8055 - Datasheet 3901008055 Page 5 of 20 May 2004 Rev 005 TH8055 Single Wire CAN Transceiver 2.5 VBAT INPUT pin Vehicle Battery Voltage The transceiver is fully operational as described in Table Static Characteristics over the range 5 < VBAT < 18 volts as measured between the GND pin and the VBAT pin. For 0 < VBAT < 4.95 volts, the bus is passive (not be driven dominant) and RxD is undriven (high), regardless of the state of the TxD pin (undervoltage lockout). The transceiver operates in normal mode when 18V > VBat IC > 27V at 85°C for one minute. Other active modes are possible until thermal shutdown (because of increased power dissipation), the transceiver does not disturb normal communication. 2.6 CAN BUS input/output pin Wave Shaping in normal and wake up mode Wave shaping is incorporated into the transmitter to minimize EMI radiated emissions. An important contributor to emissions is the rise and fall times during output transitions at the “corners” of the voltage waveform. The resultant waveform is one half of a sin wave of frequency 50 - 65 kHz at the rising waveform edge and one quarter of this sin wave at falling or trailing edge. Wave Shaping in high speed mode Wave shaping control of the rising and falling waveform edges are disabled during high speed mode. EMI emissions requirements are waived during this mode. The waveform rise time in this mode is less than one µs. Short circuits If the CAN BUS pin is shorted to ground for any duration of time, the current is limited as specified in table “static characteristics” and an over temperature shut down circuit disables the output high side drive source transistor before the local die temperature exceeds the damage limit threshold. Loss of ground In case of a valid loss of ground condition, the LOAD pin is switched into high impedance state. The CANH transmission is continued until the undervoltage lock out voltage threshold is detected. Loss of battery In case of loss of battery (VBAT = 0 or open) the transceiver do not disturb bus communication. The maximum reverse current into power supply system doesn‘t exceed 1mA.
