High Speed CAN Transceiver

TLE9251V

Overview

Product validation

Qualified for automotive applications. Product validation according to AEC-Q100.

Description

The TLE9251V 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 TLE9251V 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. 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 TLE9251V protects the

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

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

like suppressor diodes for example.

While the transceiver TLE9251V is not supplied the bus is switched off and illustrates 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 TLE9251V provides a very low level of

electromagnetic emission (EME) within a wide frequency range. The TLE9251V 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

TLE9251V 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.

Dedicated low-power modes, like Stand-by mode provide very low quiescent currents while the device is

powered up. In Stand-by mode the typical quiescent current on VIO is below 10 µA while the device can still be

woken up by a bus signal on the HS CAN bus.

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

protect the TLE9251V and the external circuitry from irreparable damage.
