... CAN bus system includes all electrical and mechanical specifications of a CAN network. The CAN transceiver is part of the physical layer specification. Several different physical layer standards of CAN networks have been developed in recent years. The TLE7250GVIO is a High Speed CAN transceiver without a dedicated wake-up function. High-speed CAN transceivers without a wake-up function are defined by the international standard ISO 11898-2 ...

... TxD, into a differential output signal on the CAN bus, provided by the CANH and CANL pins. The receiver stage of the TLE7250GVIO monitors the data on the CAN bus and converts them to a serial, single-ended signal on the RxD output pin. A logical “low” signal on the TxD pin creates a “ ...

... NEN pin. After supplying HS CAN transceiver, the TLE7250GVIO starts in stand-by mode. The internal pull-up resistor at the NEN pin sets the TLE7250GVIO to stand-by mode by default. If the microcontroller is up and running, the TLE7250GVIO can ...

... The power-down state means that the TLE7250GVIO is not supplied. In power-down state, the differential input resistors of the receiver are switched off. The CANH and CANL bus interface of the TLE7250GVIO act as high- impedance input with a very small leakage current. The high-ohmic input does not influence the “recessive” level of the CAN network and allows an optimized EME performance of the entire CAN network ...

... A permanent “low” signal on the TxD input pin activates the TxD time-out function and deactivates the transmitter. To release the transmitter after a TxD time-out event, the TLE7250GVIO requires a signal change on the TxD input pin from logical “low” to logical “high”. 5.4 ...

... TxD RxD Figure 7 Overtemperature protection The TLE7250GVIO has an integrated overtemperature detection circuit to protect the device against thermal overstress of the transmitter. In case of an overtemperature condition, the temperature sensor will disable the transmitter (see Figure 1). After the device cools down, the transmitter is activated again (see A hysteresis is implemented within the temperature sensor ...
