LIN Transceiver

Features

• Single-wire transceiver, suitable for LIN protocol

• Compatible to LIN specification 1.2, 1.3 and 2.0

• Compatible to ISO 9141 functions

• Transmission rate up to 20 kBaud

• Very low current consumption in stand-by mode

• Wake-up from Bus

• Overtemperature protection

Description

TLE 6258-2

P-DSO-8-3, -6, -7, -8, -9

The single wire transceiver TLE 6258-2 is a monolithic integrated circuit in a P-DSO-8-3
package. It works as a n interfac e between the p rotocol controll er and the phy sical b us.
The TLE 6258-2 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.

In order to reduce the current consumption the TLE 6258-2 offers a stand-by mode. A
wake-up caused by a message on the bus sets the RxD output low until th e 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 6258-2 is designed to withstand the severe conditions of automotive
applications.

Figure 3 State Diagram

For fail safe reasons the TLE 6258-2 has already a pull-up resistor of 30 kΩ
implemented. To achieve the required timings for the dominant to recessive transition of
the bus signal an additional external termination resistor of 1 kΩ is required. It is
recommended to place this resisto r in the mas ter node. To av oid reverse curren ts 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 sys tem is supported by an additional capacitor of at le ast
1 nF in the master node (see Figure 6).

In order to reduce the current consumption the TLE 6258-2 offers a stand-by mode. This
mode is selected by switc hing the Enable Not (ENN) input high (see Figure 3). In the
stand-by mode a wake-up cau sed by a message on the bu s is indicated by s etting 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.
