TLE9255WLC

The Infineon TLE9255WLC is a High-Speed CAN (HS CAN) transceiver designed for automotive and industrial applications. It provides an interface between the physical bus layer and the CAN protocol controller, driving signals to the bus and protecting the microcontroller.

This transceiver is fully compliant with ISO 11898-2 (2016) and supports standard HS CAN data rates up to 1 MBit/s, as well as CAN FD data rates up to 5 MBit/s. It features a wide common mode range for electromagnetic immunity and very low electromagnetic emission, often allowing operation without a common mode choke. The TLE9255WLC offers excellent ESD robustness, rated at ±10 kV according to IEC 61000-4-2.

Fail-safe features include TxD timeout, overtemperature shutdown, and overtemperature warning. It also supports wake-up pattern and wake-up frame detection in low-power modes, with a wake filter time between 0.5µs and 1.8µs. The device is available in PG-DSO-14 or PG-TSON-14 packages and is qualified for automotive applications according to AEC-Q100.

Additional features include an independent supply concept for VCC and VBAT pins, extended supply range on VCC and VIO, and CAN short circuit proofing to ground, battery, and VCC. The SPI clock frequency can reach up to 4 MHz.
