Interface - Drivers, Receivers, Transceivers

TLE7269GXUMA1 is an automotive automotive driver-receiver integrated product developed and manufactured by Infineon. It is mainly used for the transmission of data and signals between ECUs in automotive power systems. It is integrated into communication interface units for various applications. This article introduces the application field and working principle of TLE7269GXUMA1.

Applications of TLE7269GXUMA1

The TLE7269GXUMA1 is mainly used for signal transmission in electric vehicles, and is used in second bus standard applications. Such as body control coupler in smart car, electric power steering, SENT signal and electric window lift module power supply and other applications.

In the body control coupler, TLE7269GXUMA1 is mainly used to distribute power and provide data communication. This integrated product can provide several convenient functions to the body control coupler, such as communication interface, cluster and power steering control.

TLE7269GXUMA1 can also be used in smart car electric power steering modules. In this module, the high-precision MCU can accurately control the torque value, and can also provide sensing value to the system, which is necessary for realizing the goal of agile driving. This integrated product integrates the signal transmission of electric power steering into the CANFD standard, to reduce system cost and improve the efficiency of signal transmission.

Working principle of TLE7269GXUMA1

TLE7269GXUMA1 is a high-performance integrated product developed by Infineon. It adopts the improved Texas Instruments TLE7269-2GXUMA1 chip as its core, and adds a high precision filter control circuit and an LDO power control circuit. The integrated product also includes an integrated CAN driver and receiver and an integrated analog isolator.

TLE7269GXUMA1 has two CANFD physical interfaces, and a digital data receiver, which is mainly used for the connection between ECUs. TLE7269GXUMA1 uses frequency offset to ensure that signals in both directions of data transmission can be transmitted simultaneously, and at the same time, it can make up for the different levels of termination resistors of the transmitter and the receiver.

In addition, TLE7269GXUMA1 also provides built-in wake-up circuitry. When the system is in low power state, the integrated wake-up logic can be used to detect the rising edge of the signal, notify the system to wake up from the low power state, and automatically complete the wake-up processing.

Conclusion

The application of Infineon\'s TLE7269GXUMA1 extends to many fields of smart cars, such as electric power steering, body control coupler and electric window lift module power supply. Its working principle is mainly based on the built-in wake-up circuitry, CAN driver and receiver and analog isolator. With its high performance, TLE7269GXUMA1 has become an important integrated product for automotive power system.
