General Description
The TH8080 is a physical layer device for a single wire data link capable of operating 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 which use the network. The TH8080 is designed in accordance to the
physical layer definition of the LIN Protocol Specification, Rev. 1.3 and 2.0.The IC furthermore can be used
in ISO9141 systems.
Because of the very low current consumption of the TH8080 in recessive state it’s suitable for ECU
applications with hard standby current requirements, whereby no sleep/wake up control from the
microprocessor is necessary.

3. Functional Description
3.1 Initialization
After power on, the chip enters automatically the recessive state. If the voltage regulator provides the VCC –
supply voltage, normal communication is possible.
3.2 Operating Modes
All operation modes will be handled from the TH8080 automatically.
Normal Mode
After power on, the IC switches automatically to normal mode. Bus communication is possible.
If there is no communication on the bus line the power consumption of the IC is very low and therefore it is
no standby management from the MCU necessary.
Thermal Shutdown Mode
If the junction temperature TJ is higher than 155°C, the TH8080 will be switched into the thermal shutdown
mode (bus driver will be switched off).
If TJ falls below the thermal shutdown temperature (typ. 140°C) the TH8080 will be switched to the normal
mode.
3.3 LIN BUS Transceiver
The transceiver consists a bus-driver with slew rate control, current limitation and as well in the receiver a
high voltage comparator followed by a debouncing unit.
BUS Input/Output
The recessive BUS level is generated from the integrated 30k pull up resistor in serial with a diode This
diode prevent the reverse current of VBUS during differential voltage between VS and BUS (VBUS>VS).
No additional termination resistor is necessary to use the TH8080 in LIN slave nodes. If this IC is used for
LIN master nodes it is necessary that the BUS pin is terminated via a external 1kΩ resistor in serial with a
diode to VBAT.
TxD Input
During transmission the data at the pin TxD will be transferred to the BUS driver for generating a BUS signal.
To minimize the electromagnetic emission of the bus line, the BUS driver is equipped with an integrated slew
rate control and wave shaping unit.
Transmitting will be interrupted if thermal shutdown is active.
The CMOS compatible input TxD controls directly the BUS level:
TxD = low
TxD = high
->
->
BUS = low (dominant level)
BUS = high (recessive level)
The TxD pin has an internal pull up resistor connected to VCC. This secures that an open TxD pin generates
a recessive BUS level.

The receive threshold values VBUS_CNT_max and VBUS_CNT_min are symmetrical to the centre voltage of 0.5*VS
with a hysteresis of typ. 0.175*VS. Including all tolerances the LIN specific receive threshold values of 0.4*VS
and 0.6*VS will be secure observed.
The received BUS signal will be output to the RxD pin:
BUS < VBUS_CNT – 0.5 * VHYS
BUS > VBUS_CNT + 0.5 * VHYS
->
->
RxD = low (BUS dominant)
RxD = high, floating (BUS recessive)
This pin is a buffered open drain output with a typical load of:
Resistance: 2.7 kOhm
Capacitance: < 25 pF
Datarate
The TH8080 is a constant slew rate transceiver that means the bus driver operates with a fixed slew rate
range of 0.5 V/µs ≤ ∆V/∆T ≤ 3V/µs. This principle secures a very good symmetry of the slope times between
recessive to dominant and dominant to recessive slopes within the LIN bus load range (CBUS, Rterm).
The TH8080 guarantees data rates up to 20kbit within the complete bus load range under worst case
conditions. The constant slew rate principle is very robust against voltage drops and can operate with RCoscillator systems with a clock tolerance up to ±2% between 2 nodes.

4. Operating under Disturbance
4.1 Loss of battery
If the ECU is disconnected from the battery, the bus pin is in high impedance state. There is no impact to the
bus traffic and to the ECU itself.
4.2 Loss of Ground
In case of an interrupted ECU ground connection there is no influence to the bus line.
4.3 Short circuit to battery
The transmitter output current is limited to the specified value in case of short circuit to battery in order to
protect the TH8080 itself against high current densities .
4.4 Short circuit to ground
If the bus line is shorted to negative shifted ground levels, there is no current flow from the ECU ground to
the bus and no distortion of the bus traffic occurs.
4.5 Thermal overload
The TH8080 is protected against thermal overloads. If the chip temperature exceeds the specified value, the
transmitter is switched off until thermal recovery. The receiver is still working while thermal shutdown.
4.6 Undervoltage Vcc
If the ECU regulated supply voltage is missing or decreases under the specified value, the transmitter is
switched off to prevent undefined bus traffic.

Figure 7 - Slope time and slew rate calculation in accordance to LIN 1.3
The slew rate of the bus voltage is measured between 40% and 60% of the output voltage swing (linear
region). The output voltage swing is the difference between dominant and recessive bus voltage.
dV/dt = 0.2*Vswing / (t40% - t60% )
The slope time is the extension of the slew rate tangent until the upper and lower voltage swing limits:
tslope = 5 * (t40% - t60% )
The slope time of the recessive to dominant edge is directly determined by the slew rate control of the
transmitter:
tslope = Vswing / dV/dt
The dominant to recessive edge is influenced from the network time constant and the slew rate control,
because it’s a passive edge. In case of low battery voltages and high bus loads the rising edge is only
determined by the network. If the rising edge slew rate exceeds the value of the dominant one, the slew rate
control determines the rising edge.

Figure 8 - Duty cycle calculation in accordance to LIN 2.0
With the timing parameters shown in Figure 8 two duty cycles , based on trec(min) and trec(max) can be
calculated as follows :
D1 = trec(min) / (2 * tBit)
D2 = trec(max) / (2 * tBit)
For proper operation at 20KBit/s ( tBit = 50µs) the LIN driver has to fulfil the duty cycles specified in chapter
2.4 Dynamic Characteristics for supply voltages of 7 to 18V and the defined standard loads .
Due to this simplified definition there is no need to measure slew rates, slope times, transmitter delays and
dominant voltage levels as specified in the LIN physical layer specification 1.3.
The device within the D1/D2 duty cycle range operates also in applications with reduced bus speed of
10.4KBit/s or below.
In order to minimize EME, the slew rates of the transmitter can be reduced (approximately by 2 times). Such
devices have to fulfil the duty cycle definition D3/D4 in the LIN physical layer specification 2.0. Devices within
this duty cycle range cannot operate in 20KBit/s applications.
