Seoul, June 7, 2012 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has introduced its latest high-speed CAN transceivers designed for automotive network applications: The TLE7250 family comprises the TLE7250G and the TLE7250GVIO. The TLE7250G interfaces with 5 V microcontrollers, while the TLE7250GVIO provides a voltage reference pin to support 5 V or 3.3 V microcontroller I/O interfaces. Compared to previous generations, the new transceivers offer improved electromagnetic interference (EMI) immunity in the frequency range from 1 MHz to 1 GHz and reduced electromagnetic emission (EME) between 150 kHz and 1 GHz. In addition, the devices offer excellent ESD robustness of at least ±8 kV according to IEC61000-4-2. Due to their high impedance characteristics when not in power-down mode, the TLE7250 transceiver family reduces CAN bus leakage currents to 5 µA (microamperes) in power-down mode. This, combined with their low current consumption of less than 15 µA (at 5 V standby), improves energy efficiency. The TLE7250G and TLE7250GVIO are optimized for excellent passive operation in power-down mode, making them ideally suited for mixed-supply CAN networks.

Transceivers connect all different Electronic Control Units (ECUs) in the In-Vehicle Network (IVN) architecture and play a key role in data exchange in automotive applications. As an interface between the physical bus layer and the CAN (Control Area Network) protocol controller, the TLE7250G and TLE7250GVIO drive signals on the bus and protect the microcontroller from interferences occurring within the network.

“Infineon offers a broad product range for the various bus segments, including High-Speed CAN and Low-Speed CAN as well as LIN and FlexRay,” said Frank Schwertlein, Vice President and General Manager Standard Power in the Automotive Division of Infineon Technologies AG. “Building on the success of previous generations and offering even improved robustness and energy efficiency, the new High-Speed CAN TLE7250 transceiver increases reliability at vehicle level while reducing CO2 emissions.”

All members of the TLE7250 transceiver family, including the TLE7250G and TLE7250GVIO, are based on Infineon's Smart Power Technology (SPT). SPT combines the advantages of bipolar and CMOS control circuits with DMOS power devices on the same monolithic circuit. The TLE7250G and TLE7250GVIO, as well as the SPT technology, are AEC-qualified and optimized for harsh automotive environments.

The TLE7250 transceiver family offers data rates of up to 1 Mbaud and is ideal for large CAN networks providing high data rates due to its safety features against malfunctions, optimized output slew rates of the CANH and CANL signals, and different operating modes such as normal, receive-only, and standby, each with special characteristics regarding current consumption and data transmission.

The TLE7250G and TLE7250GVIO are ISO11898-2 compliant and meet the German OEM Hardware Requirements Specification V1.3 of May 2012. Additionally, Infineon's TLE7250 transceiver family meets the latest international ESD and EMC requirements, making it suitable for use in global ECU platform designs.

The new CAN transceiver ICs offer a variety of features that ensure safety, cost-effectiveness, and efficient operation. In addition to short-circuit protection of the bus lines to GND, battery, and VCC, these devices also block vehicle transients. With a reduced short-circuit current of up to 100 mA, the TLE7250G and TLE7250GVIO can halve the current requirements of a 5 V voltage regulator while reducing associated system costs. The TxD timeout function provides a secure solution, ensuring that the CAN bus is not blocked by faulty software, microcontroller failures, or short-circuits of the TxD signal.
