... CAN bus in low power mode. This supports networks with partially un-powered nodes. The TLE6251DS has two operation modes, the normal and the stand-by mode. These modes can be chosen by the STB pin. If the TLE6251DS is in stand-by mode and a message on the bus is Type TLE6251DS ...

... TLE6251DS changes the level at the RxD pin corresponding to the bus signal (wake-up flag). The TLE6251DS is also designed to withstand the severe conditions of automotive applications and to support 12 V and 24 V applications. The IC is based on the Smart Power Technology SPT circuitry in accordance with DMOS power devices existing on the same monolithic circuit. ...

... Application Information The TLE6251DS has two operation modes, the normal and the standby mode. These modes can be controlled with the STB pin (see up there is no signal applied to STB or STB = HIGH, the standby mode is activated. To transfer the TLE6251DS into the normal mode, STB has to be switched to LOW. ...

... Transmission The signal from the µC is applied to the TxD input of the TLE6251DS. Now the bus driver switches the CANH/L output stages to transfer this input signal to the CAN bus lines. TxD Time-out Feature If the TxD signal is dominant for a time transmission of the signal at the bus. This is realized to prevent the bus from being blocked permanently dominant due to an error ...

... In normal mode the split pin is used to stabilize the recessive common mode signal. Standby Mode The standby mode is designed to switch the TLE6251DS into a low power mode with minimum current consumption. The driving stages and the receiver are deactivated. Only the relevant circuitry to guarantee a correct handling of the CAN bus wake-up is still active. This wake-up receiver is also designed to show an excellent immunity against electromagnetic noise (EMI) ...
