TLE 6259-2G Q 67006 - A 9596 P-DSO-8-3
Description
The TLE 6259-2 is a monolithic integrated circuit in a P-DSO-8-3 package. It works as an interface between the protocol controller and the physical bus. The TLE 6259-2 is especially suitable to drive the bus line in LIN systems in automotive and industrial applications. Further it can be used in standard ISO9141 systems. The TLE6259-2 has a BUS short to GND feature implemented, to avoid a battery decharge.
In order to reduce the current consumption, the TLE 6259-2 offers a sleep operation mode. In this mode a voltage regulator can be controlled to minimize the current consumption of the whole application. A wake-up caused by a message on the bus, enables the voltage regulator and sets the RxD output LOW until the device is switched to normal operation mode.
®
The IC is based on the Smart Power Technology SPT
which allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit.
The TLE 6259-2 is designed to withstand the severe conditions of automotive applications.

Master Termination
For fail safe reasons, the TLE6259-2 already has a pull up resistor of 30kW implemented. To achieve the required timings for the dominant to recessive transition of the bus signal an additional external termination resistor of 1kW is required. It is recommended to place this resistor in the master node. To avoid reverse currents from the bus line into the battery supply line in case of an unpowered node, it is recommended to place a diode in series to the external pull up. For small systems (low bus capacitance) the EMC performance of the system is supported by an additional capacitor of at least 1nF in the master node (see figure 6 and 7, application circuit).
External Capacitors
An capacitor of 22µF at the supply voltage input V
buffers the input voltage. In
S
combination with the required reverse polarity diode this prevents the device from detecting power down conditions in case of negative transients on the supply line.
Version 2.06 5 2003-02-21
Final Datasheet TLE 6259-2
The 100nF capacitors close to the VS pins of the 6259-2 and the voltage regulator help to improve the EMC behavior of the system.
Sleep Mode
In order to reduce the current consumption the TLE 6259-2 offers a sleep operation mode. This mode is selected by switching the enable input EN low (see figure 3, state diagram). In the sleep mode, a voltage regulator can be controlled via the INH output in order to minimize the current consumption of the whole application. A wake-up caused by a message on the communication bus, automatically enables the voltage regulator by switching the INH output high. In parallel the wake-up is indicated by setting the RxD output LOW. When entering the normal mode this wake-up flag is reset and the RxD output is released to transmit the bus data.
In case the voltage regulator control input is not connected to INH output or the microcontroller is active respectively, the TLE6259-2 can be set in normal operation mode without a wake-up via the communication bus.
Bus Short to GND Feature
The TLE6259-2 also has a BUS short to GND feature implemented, in order to protect the battery from running out of charge. A normal master termination connection like described above, 1kW resistor and diode between bus and V
, whould cause a
S
constantly drawn current via this path. The resulting resistance of this short to GND is lower than 1kW. To avoid this current during a generator off state, like a parked car, the sleep mode has a bus short to GND feature implemented in the 6259-2. This feature is only applicable, if the master termination is connected with the INH pin, instead of the
. For a more detailed information see the application circuit in figure 6 and 7.

Infineon goes for Business Excellence
“Business excellence means intelligent approaches and clearly defined processes, which are both constantly under review and ultimately lead to good operating results. Better operating results and business excellence mean less idleness and wastefulness for all of us, more professional success, more accurate information, a better overview and, thereby, less frustration and more satisfaction.”
