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.

Figure 3
Mode State Diagram
The IFX1050G is equipped with three different operation modes.
4.1
Normal Mode
In the Normal Mode the device is able to receive data from the CAN bus and to transmit messages to the CAN bus.
The IFX1050G enters Normal Mode by setting the INH input to logical “LOW” and the RM input to logical “HIGH”
(see Figure 3).
4.2
Stand - By Mode
Stand - By Mode is a Low - Power mode with reduced current consumption on the power supply VCC.
In Stand - By Mode the receiver and the transceiver of the IFX1050G are disabled and the device can not receive
any data from the CAN bus, nor transmit any data to the CAN bus. The IFX1050G enters Stand - By Mode by
setting the INH input to logical “HIGH” (see Figure 3).
When the Stand - By mode is not used the INH pin has to be connected to GND in order to switch the IFX1050G
permanently into Normal Mode.
4.3
Receive - Only Mode
The Receive - Only Mode can be used for diagnostic purposes (to check the bus connections between the nodes)
as well as to prevent the bus being blocked by a faulty permanent dominant TxD input signal. In Receive - Only
Mode the output stage of the transceiver IFX1050G is disabled. The IFX1050G can not send any data to the
CAN bus, but is still able to receive data from the CAN bus. The IFX1050G enters Receive - Only Mode by setting
the RM input and the INH input to logical “LOW” (see Figure 3).
In case the Receive - Only Mode is not used, the RM pin can be left open or it can be also connected to the power
supply VCC.

Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
