TLE9255W

HS CAN Transceiver with Partial Networking

Overview

Description

As an interface between the physical bus layer and the CAN protocol controller, the TLE9255W drives the

signals to the bus and protects the microcontroller from interference generated within the network. Based on

the high symmetry of the CANH and CANL signals, the TLE9255W provides a very low level of electromagnetic

emission within a wide frequency range, allowing the operation of the TLE9255W without a common mode

choke in automotive and industrial applications.

The TLE9255W is enclosed in an RoHS compliant PG-DSO-14 or PG-TSON-14 package and fulfills the

requirements of the ISO11898-2 (2016).

The TLE9255W is part of the Infineon standard HS CAN transceiver family and provides beside CAN partial

networking functions also a CAN FD capability up to 5 MBit/s in HS CAN networks. Configured as a partial

networking HS CAN transceiver the TLE9255W can drive and receive CAN FD messages. it can also be used to

block the payload of CAN FD messages. This CAN FD tolerant feature allows the usage of microcontrollers in

CAN FD networks, which are not CAN FD capable.

The SPI of TLE9255W controls the setup of the wake-up messages and the status message generated by the

internal state machine. Most of the functions, including wake-up functions, INH output control, mode control,

undervoltage control are configurable by the SPI. This allows a very flexible usage of the TLE9255W in different

applications.

The two non-low power modes (Normal-operating Mode and Receive-only Mode) and the two low power

modes (Sleep Mode and Stand-by Mode) provide minimum current consumption based on the required

functionality.

In Sleep Mode the TLE9255W can detect a wake-up pattern (WUP) on the HS CAN and then change the mode

of operation accordingly; even at a quiescent current below 26 µA over the full temperature range.

In Selective-wake Sub-mode the TLE9255W monitors the CAN messages on the HS CAN bus. If the TLE9255W

detects a matching wake-up frame, then it triggers a mode change. The TLE9255W monitors wake-up

identifiers up to 29 bit as well as up to 64 bit wide data. The internal protocol handler counts all bus errors. The

SPI indicates failures, error counter overflow and synchronization failures to the microcontroller.

The unique power-supply management allows the application to use the TLE9255W without the battery

supply VBAT connected. In this case the TLE9255W is supplied over the VCC pin. The VIO voltage reference

supports 3.3 V and 5 V supplied microcontrollers.

Based on Infineon Smart Power Technology (SPT), the TLE9255W provides excellent immunity together with

a very high electromagnetic immunity (EMI). The TLE9255W and the Infineon SPT are AEC qualified and

tailored to withstand the harsh conditions of the automotive environment.
