TLE7251V
High Speed CAN-Transceiver with Bus Wake-up
Overview
Description
The TLE7251V is a transceiver designed for HS CAN networks in automotive and industrial applications. As an
interface between the physical bus layer and the CAN protocol controller, the TLE7251V drives the signals to
the bus and protects the microcontroller against interferences generated within the network. Based on the
high symmetry of the CANH and CANL signals, the TLE7251V provides a very low level of electromagnetic
emission (EME) within a wide frequency range.
The TLE7251V is available in a small, leadless PG-TSON-8 package and in a PG-DSO-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). The TLE7251VLE and the TLE7251VSJ are fulfilling or
exceeding the requirements of the ISO11898-2.
The TLE7251V provides a digital supply input
V
IO
and a stand-by mode. It is designed to fulfill the enhanced
physical layer requirements for CAN FD and supports data rates up to 2 MBit/s.
On the basis of a very low leakage current on the HS CAN bus interface the TLE7251V provides an excellent
passive behavior in power-down state. These and other features make the TLE7251V exceptionally suitable for
mixed supply HS CAN networks.
Based on the Infineon Smart Power Technology SPT, the TLE7251V provides excellent ESD immunity together
with a very high electromagnetic immunity (EMI). The TLE7251V and the Infineon SPT technology are
AEC qualified and tailored to withstand the harsh conditions of the automotive environment.
Two different operating modes, additional fail-safe features like a TxD time-out and the optimized output slew
rates on the CANH and CANL signals make the TLE7251V the ideal choice for large HS CAN networks with high
data transmission rates.
