1.1
• Single-wire transceiver, suitable for LIN protocol
• Compatible to LIN specification
• Compatible to ISO 9141 functions
• Transmission rate up to 20 kBaud
• Very low current consumption in stand-by mode
• Short circuit proof to ground and battery
• Overtemperature protection
Type
TLE 6258 G
Description
The single-wire transceiver TLE 6258 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 6258 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 offers a stand-by mode. A
wake-up caused by a message on the bus sets the RxD output low until the device is
switched to normal operation mode.
The IC is based on the Siemens Power Technology SPT
CMOS control circuitry in accordance with DMOS power devices existing on the same
monolithic circuit.
The TLE 6258 is designed to withstand the severe conditions of automotive applications.
