• Manufacturer Part Number: TLE 7259-2GU
• Manufacturer: Infineon Technologies

Specifications of TLE 7259-2GU

• Packages: PG-DSO-8
• Transmission Ratemax: 10.4 kbit/s
• Quiescent Current (max.): < 10 µA sleep mode
• Bus Wake-up Capability: Yes
• Additional Features: INH, EN, WK
• Wake-up Inputs: Bus wake-up + wake-up pin

This feature is only applicable, if the master termination of the LIN bus is connected to the INH pin instead of being
connected to the power supply V
from the power supply V
A separate Master Termination Switch is implemented at pin BUS, to avoid a voltage drop on the recessive level
of LIN bus, in case of a dominant level or a short to ground on at the LIN bus.

The device fulfills the Physical Layer Specification of LIN 1.2, 1.3, 2.0 and 2.1.
The differences between LIN specification 1.2 and 1.3 is mainly the physical layer specification. The reason was
to improve the compatibility between the nodes.
The LIN specification 2.0 is a super set of the 1.3 version. The 2.0 version offers new features. However, it is
possible to use the LIN 1.3 slave node in a 2.0 node cluster, as long as the new features are not used. Vice versa
it is possible to use a LIN 2.0 node in the 1.3 cluster without using the new features.
In terms of the physical layer the LIN 2.1 Specification doesn’t include any changes and is fully compliant to the
LIN Specification 2.0.
LIN 2.1 is the latest version of the LIN specification, released in December 2006.

The TLE7259-2GU is EME (Electro - Magnetic - Emission) optimized for the requirements of the US automotive
market. The timings of the TLE7259-2GU are compliant to the SAE J2602-2 standard.
