Description
The IFX1050G is optimized for high speed differential mode data transmission in industrial applications and it is
compliant to ISO11898-2. The transceiver IFX1050G works as an interface between the CAN protocol controller
and the physical differential bus in High Speed CAN applications. It supports data transmission rates from 1 kBaud
up to 1 MBaud.
The IFX1050G has three different operation modes:
The Normal Mode, the Receive - Only Mode and the Stand - By Mode. The mode selection is controlled by the
logical input pins RM and INH.
The IC is based on the
Smart Power Technology
SPT
®
which allows bipolar and CMOS control circuitry in
accordance with DMOS power devices existing on the same monolithic circuit. The IFX1050G is designed to
withstand the severe conditions in industrial applications and provides excellent EMC performance within a broad
frequency range.
