... The TLE7250G is integrated in a RoHS compliant PG-DSO-8 package and fulfills or exceeds the requirements of ISO 11898- successor to the first generation of HS CAN transceivers, the pin assignment and function of the TLE7250G is fully compatible with its predecessor model, the TLE6250G. The TLE7250G is optimized to provide an excellent passive behavior in the power-down state ...

... Block diagram Note: In comparison with theTLE6250G, the pin 8 (INH) was renamed as NEN, but the function remains unchanged. NEN stands for NotENable. The name of pin 5 has been changed from RM (TLE6250G) to NRM on the TLE7250G. The function of pin 5 remains unchanged. Data Sheet Output Temp- ...

... The CAN transceiver is part of the physical layer specification. Several different physical layer definitions of CAN networks have been developed in recent years. The TLE7250G 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 TLE7250G 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 “ ...

... V supplying to the HS CAN transceiver, the TLE7250G starts in stand-by mode. The internal pull-up resistors CC set the TLE7250G to stand-by mode by default. If the microcontroller is up and running, the TLE7250G can switch to any mode of operation within the time period for mode change undervoltage detection on V NRM = 1 ...

... The power-down state means that the TLE7250G is not supplied. In power-down state, the differential input resistors of the receiver stage are switched off. The CANH and CANL bus interface of the TLE7250G acts 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 TLE7250G requires a signal change on the TxD input pin from logical “low” to logical “high”. 5.4 ...

... TxD RxD Figure 7 Overtemperature protection The TLE7250G 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 ...
