Description

The TLE 7259 G 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 7259 G is

especially suitable to drive the bus line in LIN systems in automotive and industrial

applications.

In order to reduce the current consumption, the TLE 7259 G offers a sleep operation

mode. In this mode the voltage regulator can be switched off by the TLE 7259 G to

minimize the current consumption of the whole application. A wake-up caused by a

message on the bus or a signal at the wake (WK) pin, enables the voltage regulator and

sets the device to standby operation mode. The TLE 7259 G has a BUS short to GND

feature implemented, to avoid a battery discharge.

The TLE 7259 G offers a very good EMC performance within a broad frequency range

independent from battery voltage. This is achieved by implementing a slope control

mechanism based on a constant slew rate. The TLE 7259 G can also be used with 3.3

V and 5 V micro controllers.
