Type Ordering Code Package
TLE 6258 G Q67006-A9469 P-DSO-8-3
The single-wire transceiver TLE 6258 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 6258 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.
In order to reduce the current consumption the TLE 6258 offers a stand-by mode. A wake-up caused by a message on the bus sets the RxD output low until the device is switched to normal operation mode.
®
The IC is based on the Siemens Power Technology SPT
which allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit.
The TLE 6258 is designed to withst and the severe c onditions of automotive applic ations.

Figure 3: State Diagram
For fail safe reasons the TLE6258 has already a pull up resistor of 30kΩ implemented. To achieve the re quired ti mings for t he dominan t to reces sive tr ansition of the bus signal an additional exter nal terminat ion resistor of 1k is required. It is recommen ded 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 unpower ed nod e, it i s recommende d to pl ace a di ode 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, application circuit).
In order to reduce the current consumption the TLE 6258 offers a stand-by mode. This mode is selected by switching the Enable Not (ENN) input high (see figure 3, state diagram). In the st and-by mode a wake-up caused by a message o n the bus i s indica ted by setting the RxD out put low. When en tering th e normal mode th is wake-up fl ag is reset and the RxD output is released to transmit the bus data.
