HS CAN Transceiver

High Speed CAN Transceiver

Overview

Description

The TLE9250 is the latest Infineon high-speed CAN transceiver generation, used inside HS CAN networks for

automotive and also for industrial applications. It is designed to fulfill the requirements of ISO 11898-2 (2016)

physical layer specification and respectively also the SAE standards J1939 and J2284.

The TLE9250 is available in a PG-DSO-8 package and in a small, leadless PG-TSON-8 package. Both packages

are RoHS compliant and halogen free. Additionally the PG-TSON-8 package supports the solder joint

requirements for automated optical inspection (AOI).

As an interface between the physical bus layer and the HS CAN protocol controller, the TLE9250 protects the

microcontroller against interferences generated inside the network. A very high ESD robustness and the

perfect RF immunity allows the use in automotive application without adding additional protection devices,

like suppressor diodes for example.

While the transceiver TLE9250 is not supplied the bus is switched off and illustrate an ideal passive behavior

with the lowest possible load to all other subscribers of the HS CAN network.

Based on the high symmetry of the CANH and CANL output signals, the TLE9250 provides a very low level of

electromagnetic emission (EME) within a wide frequency range. The TLE9250 fulfills even stringent EMC test

limits without additional external circuit, like a common mode choke for example.

The perfect transmitter symmetry combined with the optimized delay symmetry of the receiver enables the

TLE9250 to support CAN FD data frames. Depending on the size of the network and the along coming parasitic

effects the device supports bit rates up to 5 MBit/s.

Fail-safe features like overtemperature protection, output current limitation or the TxD time-out feature

protect the TLE9250 and the external circuitry from irreparable damage.
