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.

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 155C, 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. 140C) 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 1k 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. TH8080 - Datasheet 3901008080 Page 10 of 23 July 2004 Rev 006 TH8080 SoloLIN Transceiver RxD Output The data signals from the BUS pin will be transferred continuously to the pin RxD. Short spikes on the bus signal are suppressed by the implemented debouncing circuit. VS VBUS_CNT_max 60% 50% 40% VhHYS BUS VBUS_CNT_min t < trec_deb t < trec_deb RxD Figure 6 - Receive impulse diagram 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/s V/T 3V/s. 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. TH8080 - Datasheet 3901008080 Page 11 of 23 July 2004 Rev 006 TH8080 SoloLIN Transceiver 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.

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.

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.

Assembly Information This Melexis device is classified and qualified regarding soldering technology, solderability and moisture sensitivity level, as defined in this specification, according to following test methods: IPC/JEDEC J-STD-020 Moisture/Reflow Sensitivity Classification For Nonhermetic Solid State Surface Mount Devices (classification reflow profiles according to table 5-2) EIA/JEDEC JESD22-A113 Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing (reflow profiles according to table 2) CECC00802 Standard Method For The Specification of Surface Mounting Components (SMDs) of Assessed Quality EIA/JEDEC JESD22-B106 Resistance to soldering temperature for through-hole mounted devices EN60749-15 Resistance to soldering temperature for through-hole mounted devices MIL 883 Method 2003 / EIA/JEDEC JESD22-B102 Solderability For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis. The application of Wave Soldering for SMD's is allowed only after consulting Melexis regarding assurance of adhesive strength between device and board. Based on Melexis commitment to environmental responsibility, European legislation (Directive on the Restriction of the Use of Certain Hazardous substances, RoHS) and customer requests, Melexis has installed a roadmap to qualify their package families for lead free processes also. Various lead free generic qualifications are running, current results on request.
