描述 Description

The TLE7250G is a transceiver designed for High Speed CAN networks in automotive and industrial applications.As an interface between the physical bus layer and the CAN protocol controller, the TLE7250G 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 TLE7250G provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE7250G is integrated in a RoHS compliant PG-DSO-8 package and fulfills or exceeds the requirements of ISO 11898-2. As a successor to the first generation of HS CAN transceivers, the pin assignment and function of the TLE7250G is fully compatible with its predecessor model, the TLE6250G. The TLE7250G is optimized to provide an excellent passive behavior in the power-down state. This feature makes the TLE7250G extremely suitable for mixed supply CAN networks. Based on the Infineon Smart Power Technology SPT, the TLE7250G provides excellent ESD immunity together with a very high electromagnetic immunity (EMI). The Infineon Smart Power Technology SPT allows bipolar and CMOS control circuitry in accordance with DMOS power devices to exist on the same monolithic circuit. The TLE7250G and the Infineon SPT technology are AEC qualified and tailored to withstand the harsh conditions of the Automotive Environment. Three different operating modes, additional fail-safe features like TxD time-out and the optimized output slew rates  on the CANH and CANL signals make the TLE7250G the ideal choice for large CAN networks with high data transmission rates.
