Description
The TLE9254V is part of Infineons high speed CAN transceiver generation, used in HS CAN for automotive
applications as well as in industrial applications. It is designed to fulfill the requirements of the following
standards:
ISO 11898-2 (2016) physical layer specification

High speed dual CAN transceiver with bus wake-up
Description
SAE J1939
SAE J2284
The TLE9254V is available in a PG-DSO-14 package and in a small, leadless PG-TSON-14 package. Both packages
are RoHS compliant and halogen free. Additionally the PG-TSON-14 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 TLE9254V is designed to
protect the microcontroller against interference generated inside the network. A very high ESD robustness and
the very high RF immunity allow the use in automotive applications without additional protection devices, such
as suppressor diodes.
The very high transmitter symmetry combined with the optimized delay symmetry of the receiver enables the
TLE9254V to support CAN FD data frames up to 5 Mbit/s. Based on the high symmetry of the CANH and CANL
output signals, the TLE9254V provides a very low level of electromagnetic emission (EME) within a wide
frequency range. The TLE9254V fulfills even stringent EMC test limits without external components, such as a
common mode choke.
TLE9254V offers low-power management using the stand-by mode with an optimized, very low quiescent
current. In stand-by mode the typical quiescent current for one channel of the TLE9254V is below 10 A, while
the CAN channel can still wake up on a signal on the HS CAN bus.
Fail-safe features such as overtemperature protection, output current limitation or the TxD timeout feature are
designed to protect the TLE9254V and the external circuitry from irreparable damage.
While the transceiver TLE9254V is not supplied, the bus is switched off and exhibits an ideal passive behavior
with the lowest possible load to all other subscribers of the HS CAN network.
TLE9254V supports 3.3 V as well as 5 V supplied microcontrollers with the V .
