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.

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.
