TCAN1042GDRBRQ1 Application Field and Working Principle

As an Interface - Drivers, Receivers, Transceivers, the TCAN1042GDRBRQ1 is a cost effective and highly integrated CAN transceiver for automotive applications. The device provides differential receivers for higher electromagnetic compatibility and allows reliable communication of Node to Node (N2N) messages. This article will provide a detailed overview of the application field and working principle of the TCAN1042GDRBRQ1.

Application Fields

The TCAN1042GDRBRQ1 is ideally suited for automotive applications such as in-vehicle networks and other industry control networks. The device is used in systems where a single CAN transceiver is required and is widely used in automotive applications, including engine control and transmission control systems, as well as in vehicle navigation, airbag control and infotainment systems. It provides reliable bus communication when used in a pair with other CAN transceivers.

Working Principle

The TCAN1042GDRBRQ1 operates as an open drain transceiver with differential receivers for better electromagnetic compatibility (EMC). It provides a differential voltage of up to 3V for improved noise immunity and high speeds. The device is also capable of operating in the low-power sleep mode for improved energy efficiency. The device operates at 2.7-5.5V and provides a data rate of up to 1 Mbps. It supports two independent channels with a total power consumption of 60mW. The device features two pipeline receivers, two transmitters, two differential receivers and two serial data interfaces. The device supports a peak coupling-capacitance up to 1500pF and provides a differential voltage of 3V. The device has protection circuits to protect the CAN bus against short-circuit, over-voltage and under-voltage. It has built-in watch dogs to protect the device against data transmission errors during high speed conditions. The device also features error detection and error signalling features to ensure reliable communications.The device supports various error detection features, such as Bit Error Detection (BED) and Digital Error Detection (DED). BED checks for single-bit errors in the CAN message and DED checks for multi-bit errors in the CAN message. There is also a Wake-up feature that can be used to detect faults on the CAN bus and transmit an error frame in response.

Conclusion

The TCAN1042GDRBRQ1 is a cost-effective and highly integrated CAN transceiver for automotive applications. It is used in systems where a single CAN transceiver is required and is widely used in engine control, transmission control, vehicle navigation, airbag control and infotainment systems. The device provides differential voltage of up to 3V for improved noise immunity and high speeds. It also supports two independent channels with a total power consumption of 60mW. The device features two pipeline receivers, two transmitters, two differential receivers and two serial data interfaces, as well as protection circuits and various error detection features.
