Description

The TLE7259G 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 TLE7259G 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.

TLE7259G 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.
