TLE62592GXUMA1

Drivers, Receivers, Transceivers Overview

The TLE6259-2 is a monolithic single-wire LIN transceiver designed for automotive and industrial applications. It operates with a battery supply voltage (VS) range of 6V to 35V and a logic supply (VCC) of 4.5V to 5.5V. The device supports transmission rates up to 20 kBaud and complies with LIN specification 1.2 and ISO 9141 functions. Key electrical characteristics include a typical current consumption of 0.7 mA in normal mode recessive state and as low as 18 µA in standby mode. It features integrated bus short-to-ground protection, overtemperature shutdown at approximately 170°C, and an INH output for controlling external voltage regulators.

Drivers, Receivers, Transceivers FAQ

How does the TLE6259-2 handle bus short-to-ground conditions?

The device implements a specific feature to limit current draw when the bus is shorted to ground, preventing battery depletion during parked states, provided the master termination is connected correctly to the INH pin.

What is the function of the INH pin?

The INH pin serves as an inhibit output that goes HIGH during a bus wake-up event. It is used to control an external voltage regulator to manage power consumption in sleep and standby modes.

Is the TLE6259-2 compatible with LIN specification 1.2?

Yes, the datasheet explicitly states that the transceiver is compatible with LIN specification 1.2.
