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.
