General Description

The TH8056 is a physical layer device for a single wire data link capable of operating with various CSMA/CR protocols
such as the Bosch Controller Area Network (CAN) version 2.0. This serial data link network is intended for use in
applications where a high data rate is not required and a lower data rate can achieve cost reductions in both the physical
media components and 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 the 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.

The bit rate for normal communications is typically 33.33kbit/s, for high speed transmissions like described above a
typical bit rate of 83.33kbit/s is recommended. The TH8056 is designed in accordance to the Single Wire CAN Physical
Layer Specification GMW3089 V2.1 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

3.1 TxD Input pin

Logic command to transmit on the single wire CAN bus

TxD Polarity

TxD = logic 1 (or floating) on this pin produces an undriven or recessive bus state (low bus voltage)
TxD = logic 0 on this pin produces 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 Mode 0,1 pins are in the 0,0 or sleep state, the transceiver
cannot drive the CAN Bus pin to the dominant state.
The transceiver provides an internal pull up 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 for 3.3V and 5V supply voltages.

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.

3.2 Mode 0 and Mode 1 pins

Select transceiver operating modes

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 for 3.3V and 5V supply voltages.

Figure 5 - Truth Table

Mode 0 = 0, Mode 1 = 0 - 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 CAN Bus pin is not in the dominant state regardless of the state of the
TxD pin.

Mode 0 = 1, Mode 1 = 0 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 transmitters which require communicating in high speed mode are able to drive
reduced bus resistance during this mode.

Mode 0 = 0, Mode 1 = 1 - Transmit with high voltage signals to wake up remote nodes (HVWU)
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 does not disturb the sleeping nodes.

Mode 0 = 1, Mode 1 = 1 - Normal speed and signal voltage mode
Transmission bit rate in normal communication is 33.333 Kbits/sec. In normal transmission mode the
TH8056 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.

3.3 RxD Output pin

Logic data as sensed on the single wire CAN bus

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 does 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 signal awakens the
transceiver, the RxD pin signalises an interrupt (logic 0 for dominant high-voltage signal). If there is no mode
change within the time stated (typically 250ms), the transceiver reenters the sleep mode as described in 3.7

When not in sleep mode all valid bus signals will be sent out on the RxD pin.

RxD Typical Load

Resistance: 2.7 kohms
Capacitance: < 25 pF

3.4 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 V

from the LOAD pin when in a loss of

ground state is 50 uA over all operating temperatures and 3.5 V < V

batt

< 27 V.

Vehicle Battery Voltage

The transceiver is fully operational as described in chapter 2 over the range 5V<V

batt IC

<18V as measured

between the GND pin and this pin.
For 5V < V

batt IC

< 6V the bus operates in all active modes with reduced dominant output voltage. High

voltage wake-up call is not possible (dominant output voltage is the same as in normal or high-speed mode).
The transceiver operates in normal mode when 18V < V

batt IC

< 27V at 85°C for one minute.

For 0V< V

bat IC

< 4.8V, the bus is passive (not driven dominantly) and RxD is undriven (high), regardless of

the state of the TxD pin (undervoltage lockout).

3.6 CAN

BUS

pin

Bus Input/Output

Wave Shaping in normal and HVWU 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 sine wave of frequency 50 - 65 kHz at the rising waveform
edge and one quarter of this sine wave at falling or trailing edge.

Short circuits

If the CAN BUS pin is shorted to ground for any duration of time, the current is limited to the specified value,
until 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 an ECU 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 does not disturb bus communication. The
maximum reverse current into power supply system doesn't exceed 500µA.

3.7 INH

Pin

This Pin is a high voltage highside switch used to control the ECU's regulated microcontroller voltage supply.
After power-on the transceiver automatically enters an intermediate standby mode, the INH output will
become HIGH (VBAT) and therefore the external voltage regulator will provide the Vcc supply for the ECU .
If there is no mode change within the time stated (typically 250ms), the transceiver reenters the sleep mode
and the INH output goes to logic 0 (floating). When the transceiver has detected a valid wake-up condition
(bus HVWU traffic which exceeds the wake-up filter time delay) the INH output will become HIGH (VBAT)
again and the same procedure starts as described after power-on. In case of a mode change into any active
mode the sleep timer is stopped and INH keeps high (VBAT) level. If the transceiver enters the sleep mode
(M0,1=0), INH goes to logic 0 (floating) no sooner than typically 250ms when no wake-up signal is present .
