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.
