The device is suitable to supply microcontrollers and driving a LIN bus at the same time. The TLE8458 is pin compatible to stand-alone LIN transceivers like the TLE7259-3GE. The combination of a voltage regulator and a LIN transceiver on one circuit decreases the quiescent current for a typical application to a value of 8 μA, while the TLE8458 is still able to wake-up off a LIN bus signal or a signal change on the local wake-up input WK. Compliant to all LIN standards and with a wide operational supply range, the TLE8458 can be used in all automotive applications. Based on the Infineon Smart Power Technology SPT®, the TLE8458 provides excellent ESD robustness together with a very high electro-magnetic immunity (EMI). The TLE8458 reaches a very low level of electro-magnetic emission (EME) within a broad frequency range. The TLE8458 family and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh conditions in the automotive environment.

Sub-operation modes with different slew rates on the BUS pin: • Normal Slope Mode, for data transmission rates up to 20 kBaud • Software Flash mode, for programming of the external microcontroller The operation mode of the TLE8458 is selected by the EN pin and the TxD pin. (see Table 5, see Figure 4).

The external termination could be a pull-up resistor or an active microcontroller output.

The TLE8458 enters automatically the Stand-By Mode after a Power-up. By setting the EN pin to HIGH, the operation mode changes to Normal Operation Mode, regardless of the signal applied to the TxD pin. The TLE8458 can be transferred to Stand-By mode by the following options: • After Power-up on the supply VS, the TLE8458 starts in Stand-By Mode. • From Sleep Mode or from Stop Mode the TLE8458 changes to Stand-By Mode if a Wake-up event occurs on the LIN bus. • From Sleep Mode or from Stop Mode the TLE8458 changes to Stand-By Mode if a Wake-up event occurs on the local Wake input WK. • In case of an undervoltage event on VS, the TLE8458 changes to Stand-By Mode regardless of selected operation mode. In Stand-By mode the external power supply VCC is active and LIN bus output stage is disabled. The TLE8458 provides the following functionality in Stand-By Mode: • The power supply VCC is active and functional. • The LIN transceiver output stage is disabled, no communication to the LIN bus is possible. • The LIN transceiver bus input receiver is disabled. • The LIN bus is terminated by the 30 kΩ. • Both digital pins, the TxD pin and the RxD pin act as output pins and indicate a Wake-up or a Power-up event2). • The EN input pin is active. By setting the EN pin to HIGH the TLE8458 changes the operation mode to Normal Operation Mode (see Figure 3). • The Wake-up logic is disabled. Wake-up events don’t trigger an operation mode change. Table 6 Logic table for Wake-up monitoring1) Power-up Wake-up event RxD TxD2) Comments Yes No HIGH LOW Power Up event No Via LIN Bus LOW HIGH Wake-up via LIN Bus No Via WK Pin LOW LOW Wake-up via local Wake pin WK 1) The Wake-up monitor is only active in Stand-By Mode 2) The TxD input needs an external termination to indicate a “High” or a “Low” signal. The external termination could be a pullup resistor or an active microcontroller output. 5.2.2 Normal Operation Mode The TLE8458 enters the Normal Operation Mode after the microcontroller sets EN to “High” (see Figure 4). In Normal Operation mode the LIN bus receiver and the LIN bus transmitter are active. The TLE8458 converts the logical HIGH and LOW signals on the TxD input pin to DOMINANT and RECESSIVE signals to the LIN bus. Simultaneously the input receiver of the TLE8458 converts the DOMINANT and RECESSIVE signals on the LIN bus to HIGH and LOW signals to the RxD output. In Normal Operation mode the output voltage VCC is active and the bus termination is set to 30 kΩ. Normal Slope Mode and the Software Flash Mode are Normal Operation Modes. In these two sub-modes the behavior of the power supply VCC and the bus termination are the same. Per default the TLE8458 always enters into Normal Slope Mode, either from Sleep Mode, Stop Mode or from Stand-By Mode. The Software Flash Mode can only be entered from Normal Slope mode. Data Sheet 11 Rev. 1.1, 2014-04-01 TLE8458 Mode Control In order to avoid any bus disturbance during a mode change, the output stage of the TLE8458 is disabled and set to recessive state during the mode change procedure. To release the TLE8458 for data communication on the LIN bus, the TxD pin needs to be set to HIGH for the time ttorec after the operation mode change. 5.2.2.1 Normal Slope Mode In Normal Slope Mode the maximum data transmission rate of the LIN transceiver is limited by the slope control mechanism of LIN output signal. The limitation of the slew rate of the LIN output signal results in an optimized radiated emission fulfilling automotive EMC requirements. The data transmission rate of the TLE8458G and the TLE8458GV33 is limited to 20 kBaud in Normal Operation Mode and the devices are compliant to the specification LIN2.1. 5.2.2.2 Software Flash Mode Software Flash Mode is a Normal Operation Mode and it is possible to transmit data to the LIN bus and receive data from the LIN bus. The slope control mechanism of the LIN transmitter output stage is disabled and therefore it is possible to reach higher data transmission rates, disregarding the EMC limitation of the LIN network. The Software Flash Mode can be used for programming the external microcontroller via the LIN bus, got example during the production flow of the ECU. The Software Flash Mode can only be entered from Normal Slope Mode (see Figure 3). By setting the EN pin to low for the time tfl1 and by generating a falling and a rising edge at the TxD pin with the time tfl2 and tfl3 during the low phase of the EN pin, the TLE8458 changes to the Software Flash Mode (see Figure 5). Vice versa, the TLE8458 changes from Software Flash Mode to Normal Slope Mode by applying the same sequence to the EN pin and the TxD pin. In any case, regardless if the device is in Normal Slope Mode or in Software Flash Mode, a LOW signal on the EN pin changes the operation mode to Sleep Mode or Stop Mode. The slope control mechanism will be activated, when the device changes to the Normal Operation Mode again.

The following functions are available in Stop Mode: • The power supply VCC is active and functional. • The LIN transceiver output stage is disabled, no communication to the LIN bus is possible. • The LIN transceiver input receiver is disabled. • The internal LIN bus termination is switched off. • The TxD input and the RxD output is inactive. • The EN input is active. A HIGH signal on the EN pin changes the operation mode to Normal Operation Mode. • The LIN bus Wake-up receiver is active, a Wake-up event on the LIN bus changes the operation mode to Stand-By Mode. • The wake input WK is active, a Wake-up event on the WK pin changes the operation mode to Stand-By Mode. Entering Stop Mode is only possible from the Normal Operation Mode, regardless if the device is in Normal Slope Mode or Software Flash Mode. Setting the signal on the EN pin to LOW, followed by a LOW signal on the TxD pin for the time tMode1 changes the operation mode to Stop Mode (see Figure 4). 5.2.4 Sleep Mode The Sleep Mode is a Low Power Mode as well, in comparison to the Stop Mode, the quiescent current of the TLE8458 is even further reduced. In Sleep Mode the TLE8458 is able as well to recognized Wake-up events. The Wake-up behavior in Sleep Mode is the same as in Stop Mode. The only difference between Sleep Mode and Stop Mode is, that in Stop Mode the output voltage VCC is active, in Sleep Mode the output voltage VCC is disabled. Sleep Mode can be entered from Normal Operation Mode by setting the EN pin to LOW and simultaneously setting the TxD pin to HIGH for the time tMode1 (see Figure 4). The Sleep Mode can be also entered from Stop Mode, by setting the signal on the TxD pin to HIGH for the time tMode1. 5.2.5 Wake-up Events in Sleep and Stop Mode A Wake-up event in Sleep Mode or Stop Mode changes the operation mode of the TLE8458 to Stand-By Mode. There are 3 different options to Wake-up the TLE8458 from Sleep Mode or Stop Mode: • A bus Wake-up event, caused by a message on the LIN bus. • A local Wake-up event, caused by a logical LOW signal on the WK pin. • A signal change to logical HIGH on the EN pin. Data Sheet 13 Rev. 1.1, 2014-04-01 TLE8458 Mode Control 5.2.5.1 Bus Wake-up Event A falling edge on the LIN bus, followed by a dominant bus signal for the time t > twk,Bus causes a bus Wake-up or also called remote Wake-up. The mode change becomes active with the following rising edge on the LIN bus (see Figure 6). In Stand-By Mode the Wake-up source is indicated by the TxD and RxD pins (see Table 6). LIN BUS Signal VBUS VBUS,wk VBUS,dom tWK,Bus Sleep Mode Stand-By Mode Stop Mode Stand-By Mode VCC VCC Note: In Sleep Mode the Output Voltage VCC is disabled and will be actived by a mode change to Stand-By Mode. In Stop Mode the Output Voltage VCC is active and remains active after the mode change to Stand-By Mode. Figure 6 Bus Wake-up 5.2.5.2 Local Wake-up Event A Wake-up via LOW signal on the pin WK is called local Wake-up. A falling edge of the signal on the pin WK followed by a LOW signal for the time t > tWK change the operation mode from Sleep Mode or Stop Mode to StandBy Mode. In the case the LOW signal is shorter then the time t < tWk, the Wake-up is ignored and the TLE8458 remains in Sleep Mode or Stop Mode. In Stand-By Mode the Wake-up source is indicated by the TxD and RxD pins (see Table 6). In order to avoid unintended Wake-up´s via the local wake pin Wk, the Wk pin should get connected by a serial resistor to the power supply Vs (see Figure 15). Before the TLE8458 enters into Sleep Mode it is required to set the Voltage on the WK pin to the Vs power supply.

In Stop Mode the Output Voltage VCC is active and remains active after the mode change to Stand-By Mode. VCC Figure 7 Local Bus Wake-up 5.2.5.3 Mode Transition via EN pin The EN pin is used for the mode selection. In case the power supply VCC is present, like in Stop Mode or Sleep Mode, the TLE8458 can be directly transferred into Normal Operation Mode by setting the EN pin to HIGH. An integrated pull-down resistor at the EN pin avoids mode changes due to floating signals on the EN input. The TLE8458 changes the operation mode to Normal Operation Mode, from Stop Mode or from Sleep Mode if the EN pin is HIGH for the time t > tMode1 (see Figure 8). An integrated hysteresis on the EN pin avoids bit toggling. The mode transition via the EN pin will not be indicated in Stand-By Mode.

Over-heating could be caused by a short circuit on the VCC power supply or by a permanent short on the LIN bus combined with a high ambient temperature. In case of an over-temperature event, the TLE8458 eliminates the root cause of the over-temperature event. Two different temperature sensors are implemented inside the TLE8458. One temperature sensor protects the voltage regulator and controls the output voltage VCC, the second temperature sensor protects the LIN transmitter output stage. In case the junction temperature on the LIN output stage raises above the threshold T > TSD,LIN, the temperature sensor disables the LIN output stage. The TLE8458 is still able to receive data from the LIN bus. If the temperature falls below the threshold, T < TSD,LIN, the output stage will be enabled and the communication can start again. An integrated hysteresis on the temperature sensor avoids toggling during over-temperature events. An overtemperature event on the LIN bus will not cause any operation mode change. In case the junction temperature on the VCC power output stage raises above the threshold T > TSD,VCC, the temperature sensor shuts down the output voltage VCC. If the junction temperature falls below the threshold, T > TSD,VCC, the power supply VCC will be enabled again. An integrated hysteresis on the temperature sensor avoids toggling during over-temperature events.

Due to its ultra low current consumption, the TLE8458 is perfectly suited for applications permanently connected to a battery. Additionally, the regulator is switched off in Sleep Mode to achieve a very low quiescent current. The TLE8458 is equipped with protection functions against overloading, short circuits, and over temperature. 6.2 Electrical Characteristics of the Voltage Regulator Table 10 Electrical Characteristics: Voltage Regulator VS = 5.5 V to 13.5 V, Tj = -40 °C +150 °C, all voltages with respect to ground, positive current flowing into pin (unless otherwise specified) Parameter Symbol Values Unit Note / Test Condition Number Min.

Data Sheet 19 Rev. 1.1, 2014-04-01 TLE8458 LIN Transceiver 7 LIN Transceiver 7.1 Functional Description The LIN Bus is a single wire, bi-directional bus, used for in-vehicle networks. The LIN Transceiver implemented inside the TLE8458 is the interface between the microcontroller and the physical LIN Bus. (see Figure 1 and Figure 15). The digital output data from the microcontroller are driven to the LIN bus via the TxD input pin on the TLE8458. The transmit data stream on the TxD input is converted to a LIN bus signal with optimized slew rate to minimize the EME level of the LIN network. The RxD output sends back the information from the LIN bus to the microcontroller. The receiver has an integrated filter network to suppress noise on the LIN Bus and to increase the EMI (Electro Magnetic Immunity) level of the transceiver. Two logical states are possible on the LIN bus according to the LIN Specification 2.1 (see Figure 10): In dominant state, the voltage on the LIN bus is set close to the GND level. In recessive state, the voltage on the LIN bus is set close to the supply voltage VS. By setting the TxD input of the TLE8458 to LOW the transceiver generates a dominant level on the LIN interface pin. The RxD output reads back the signal on the LIN bus and indicates a dominant LIN bus signal with a logical LOW to the microcontroller. Setting the TxD pin to HIGH the transceiver TLE8458 sets the LIN interface pin LIN to the recessive level, at the same time the recessive level on the LIN bus is indicated by a logical “High” on the RxD output. Every LIN network consists of a master node and one or more slave nodes. To configure the TLE8458 for master node applications, a resistor in the range of 1 kΩ and a reverse diode must be connected between the LIN bus and the power supply VS. (see Figure 15).

To avoid any blocking of the LIN network by a local ECU the TLE8458 has an integrated Power-On reset at the supply VS and an undervoltage detection at the supply VS. In case the supply voltage VS is dropping below the Power-On reset level VS < VS,UV,PON, the TLE8458 changes the operation mode to Stand-By mode. In Stand-By mode the output stage of the TLE8458 is disabled and no communication to the LIN bus is possible. The internal bus termination remains active as well as the VCC output voltage. (see Figure 1 and Figure 11). In Stand-By mode the RxD pin indicates the low power supply condition with a logical HIGH signal. Setting the EN pin to logical HIGH changes the operation mode back to Normal Operation mode. In case the supply voltage VS is dropping below the undervoltage reset level VS < VSUV (see Figure 11), the TLE8458 disables the output and receiver stages. This feature secures the communication on the LIN bus. If the power supply VS reaches a higher level as the undervoltage reset level VS > VSUV the TLE8458 continues with normal operation. A mode change only applies if the power supply VS drops below the power on reset level (VS < VS,UV,PON).

The device remains in recessive state. The TxD time-out functions prevents the LIN bus from being blocked by a permanent LOW signal on the TxD pin, caused by a failure. The transmitter output stage is released again, after a rising edge on the TxD pin has been detected (see Figure 12).
