In the normal-operating mode, the HS CAN transceiver TLE7250GVIO sends the serial data stream on the TxD
pin to the CAN bus. The data on the CAN bus is displayed at the RxD pin simultaneously. In normal-operating
mode, all functions of the TLE7250GVIO are active:
•
•
•
•
To enter the normal-operating mode, set the NEN pin to logical “low” (see
an internal pull-up resistor to the power-supply
4.4
The stand-by mode is an idle mode of the TLE7250GVIO with optimized power consumption. In the stand-by
mode, the TLE7250GVIO can not send or receive any data. The transmitter and the receiver unit are disabled.
Both CAN bus pins, CANH and CANL are connected to GND via the input resistors.

•
To enter the stand-by mode, set the pin NEN to logical “high” (see
internal pull-up resistor to the power-supply
pin needs to be connected to GND.

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.
