Introduction

The SN65HVD1477DGKR is an automotive serial communication interface which acts as both a driver and receiver for high-speed interface communication protocols such as CAN bus, LIN bus and FlexRay. The device is manufactured by Texas Instruments and is widely used for on-board communication between electronic control units (ECUs). It is designed to be compatible with the entire automotive industry standard digital communication networks and is compliant with ISO11898-2 standards. It has protection features to guard against electrical and thermal overstress and has been qualified according to the exacting Automotive Electronics Council (AEC-Q100) specifications.

Application Fields

The SN65HVD1477DGKR is a versatile two-channel device which can be used in a wide range of automotive applications. It is primarily used to transfer data between two ECUs either over a single bus line or as a gateway between different communications links. It can also be used to convert different communication protocols into one common format. It is ideal for applications such as vehicle body control, engine control and power train control. In addition, it can be used for other automotive applications such as in-car entertainment, climate control and driver assistance systems.

Working Principle

The SN65HVD1477DGKR has two operational modes, active and passive. In active mode, the device operates as a communication interface and accepts data from the CAN bus, LIN bus or FlexRay interface. Depending on the configured protocol, the device can be configured to receive control commands, support data transmission or both. When in passive mode, the SN65HVD1477DGKR acts as an interface hub that can combine data received from other communication links and formats them into a single data packet format. The two operational modes allow the device to be used as a bridge between different protocols, allowing a smooth transition between digital communications and also acting as a gateway between communication networks.

Conclusion

The SN65HVD1477DGKR is an automotive serial communication interface that acts as both a driver and receiver, designed to be compatible with a wide range of communication protocols and automotive industry standards. It is an ideal solution for high-speed interface communication protocol applications such as vehicle body, engine and transmission control, in-car entertainment systems, climate control systems and driver assistance systems. The device has protection features to guard against electrical and thermal overstress and has been qualified with Automotive Electronics Council (AEC-Q100) standards. Its two operational modes enable the device to act as a bridge between different communication protocols and also as a gateway between communication networks.
