TLE7258LE

The Infineon Technologies TLE7258LE is a single-wire LIN transceiver suitable for in-vehicle networks. It operates at transmission rates up to 20 kbps and is compliant with ISO 17987-4, LIN specification 2.2A, and SAE J2602.

Key electrical features include compatibility with 3.3 V and 5 V microcontrollers, dominant time-out protection for the TxD pin, and protection against BUS shorts to VBAT and GND. It also incorporates over-temperature protection and supply undervoltage detection. The device exhibits very high ESD robustness (±10 kV according to IEC61000-4-2) and is optimized for high electromagnetic compatibility (EMC) with very low emission and high immunity.

In sleep mode, the TLE7258LE consumes typically less than 10 µA while retaining wake-up capability upon detecting LIN bus traffic. The very low leakage current on the BUS pin makes it suitable for partially supplied networks. It is available in PG-DSO-8 and leadless PG-TSON-8 packages, with the latter supporting automated optical inspection (AOI).

This transceiver is qualified for automotive applications according to AEC-Q100, making it robust for harsh automotive environments. Potential applications include LIN slave satellite modules, rain and light sensors, window lifters, and parking aid systems.
