TLE7259G

Product Summary

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 TLE7259G 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 TLE7259G 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 TLE7259G has a BUS short to GND feature implemented, to avoid a battery discharge. The 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 TLE7259G can also be used with 3.3 V and 5 V micro controllers.
