Description
The TLE8458G and its derivatives TLE8458GV33, TLE8458GU and TLE8458GUV33, integrate a low drop voltage
regulator and a LIN transceiver on one monolithic circuit. The device is suitable to supply microcontrollers and
driving a LIN bus at the same time. The TLE8458Gx is pin compatible to stand-alone LIN transceivers like the
TLE7259-2GE. 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 TLE8458G 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 TLE8458G can be used in all automotive applications.
Based on the Infineon Smart Power Technology SPT®, the TLE8458Gx provides excellent ESD robustness
together with a very high electro-magnetic immunity (EMI). The TLE8458Gx reaches a very low level of electromagnetic emission (EME) within a broad frequency range. The TLE8458Gx family and the Infineon SPT®
technology are AEC qualified and tailored to withstand the harsh conditions in the automotive environment.

Description of Mode Control
The TLE8458Gx has 4 major operation modes:
•
•
•
•
Normal Operation Mode
Stand-By Mode
Sleep Mode
Stop Mode
The Normal Operation mode contains 2 sub-operation modes, which differentiate by the slew rate control of the
LIN Bus signal (see Figure 3).
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 TLE8458Gx is selected by the EN pin and the TxD pin. (see Table 5, see Figure 4).

Mode Control
5.2.1
Stand-By Mode
The Stand-By Mode is an idle operation mode, which disables the communication to the LIN bus. The TLE8458Gx
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 TLE8458Gx can be transferred to Stand-By mode by the following options:
•
•
•
•
After power - up on the supply VS, the TLE8458Gx starts in Stand-By Mode.
From Sleep Mode or from Stop Mode the TLE8458Gx changes to Stand-By Mode if a Wake - Up event occurs
on the LIN bus.
From Sleep Mode or from Stop Mode the TLE8458Gx changes to Stand-By Mode if a Wake - Up event occurs
on the local Wake input WK.
In case of an under - voltage event on VS, the TLE8458Gx 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 TLE8458Gx
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 TLE8458Gx 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.

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 TLE8458Gx 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 TLE8458Gx 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 TLE8458Gx 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 TLE8458G 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.
In order to avoid any bus disturbance during a mode change, the output stage of the TLE8458Gx is disabled and
set to recessive state during the mode change procedure. To release the TLE8458Gx 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.

Normal Slope Mode
In Normal Slope Mode the maximum data transmission rate of the LIN transceiver devices TLE8458G,
TLE8458GV33, TLE8458GU and TLE8458GUV33 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
The data transmission rate of the TLE8458GU and the TLE8458GUV33 is limited to 10,4 kBaud in Normal
Operation Mode. These two devices are compliant to the SAE-J2602-2 specification.
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 TLE8458Gx changes to the Software Flash Mode (see Figure 5). Vice versa, the
TLE8458Gx 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.

5.2.3
Stop Mode
The Stop Mode is a Low Power Mode, meaning the quiescent current of the TLE8458Gx is reduced to a minimum,
while the device is still able to recognized wake - up events. 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
TLE8458Gx is even further reduced. In Sleep Mode the TLE8458Gx 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.

Wake - Up Events in Sleep and Stop Mode
A Wake - Up event in Sleep Mode or Stop Mode changes the operation mode of the TLE8458Gx to Stand-By
Mode. There are 3 different options to wake-up the TLE8458Gx 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.
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).

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 TLE8458Gx 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
TLE8458Gx 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-Temperature Protection
The TLE8458Gx is protected against thermal over-heating. 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 TLE8458Gx eliminates the root cause of the over-temperature event. Two different
temperature sensors are implemented inside the TLE8458Gx. 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 TLE8458Gx 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 over-temperature 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.

Description of Voltage Regulator
The TLE8458G has a monolithic integrated voltage regulator dedicated for microcontroller supplies under harsh
automotive environment conditions. Due to its ultra low current consumption, the TLE8458Gx 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 TLE8458Gx is equipped with protection functions against overloading,
short circuits, and over temperature.

TLE8458Gx
LIN Transceiver

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 TLE8458Gx 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
TLE8458Gx. 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 TLE8458Gx 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 TLE8458Gx 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 TLE8458Gx 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).

7.1.1
Under-Voltage Detection
A dropping power supply VS on a local ECU can effect the communication of the whole LIN network. To avoid any
blocking of the LIN network by a local ECU the TLE8458Gx has an integrated Power - On reset at the supply VS
and an Under-Voltage detection at the supply VS. In case the supply voltage VS is dropping below the Power-On
reset level VS < VS,UV,PON, the TLE8458Gx changes the operation mode to Stand-By mode. In Stand-By mode the
output stage of the TLE8458Gx 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 under - voltage reset level VS < VSUV (see Figure 11), the
TLE8458Gx 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 under - voltage reset level VS > VSUV the TLE8458Gx 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).

TxD Time - Out
If the TxD signal is dominant for the time t > ttimeout, the TxD time - out function deactivates the LIN transmitter
output stage. 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).

LIN Specifications
The LIN network is standardized by international regulations. The devices TLE8458G and the TLE8458GV33 are
compliant to the specification LIN 2.1. The physical layer specification LIN 2.1 is a super set of the previous LIN
specifications, like LIN 2.0 or LIN 1.3. The TLE8458G and the TLE8458GV33 have been qualified according to
the LIN 2.1 standard, conformance test results are available on request.
The devices TLE8458GU and TLE8458GUV33 are compliant to the physical layer standard SAE-J2602-2. The
SAE-J2602-2 standard differs from the LIN 2.1 standard mainly by the lower data rate (10.4 kbit / s) and the higher
hysteresis on the LIN output signals. The TLE8458GU and the TLE8458GUV33 have been qualified according to
the SAE-J2602-2 standard, conformance test results are available on request.

external test house (IBEE Zwickau, EMC Test report Nr. 07-11-08)
8.1.1
EMC Measurement
The EMC performance has been qualified by an external test house according to the LIN EMC Test specification
Version 1.0 (August 1, 2004). For the DPI measurements according to the LIN EMC Test Specification, Section
4.2 (ISO62132 part 1: 2006, ISO62132 part 4: 2006) the verification limit for the output voltage VCC, was set to a
limit of +/- 100 mV. External test reports are available on request.
8.2
Pin Compatibility to Stand-Alone LIN transceivers
The TLE8458G is pin - and function compatible to the single LIN transceivers like the TLE7259-2GE and its
derivative the TLE7259-2GU (see Figure 16). Instead of the INH output pin on the single LIN transceiver
TLE7259-2GE the VCC power supply output can be connected to the external microcontroller. The TLE8458G
provides the same operation modes and feature s as single LIN transceiver TLE7259-2GE.
