“Low” in “Dominant” state.
5 VIO
Digital Supply Voltage Input;
Supply voltage input to adapt the logical input and output voltage levels of the
transceiver to the microcontroller supply.
100 nF decoupling capacitor to GND required.
6 CANL
CAN Bus Low level I/O;
“Low “ in “Dominant” state.
7 CANH
CAN Bus High level I/O;

internal pull-up to VIO, “Low” for Normal Operation mode.
1) The naming of pin 8 is different between the TLE8250GVIO and its forerunner model the TLE6250GV33. The function of
pin 8 remains the same.

5.4 Under-Voltage detection
The HS CAN Transceiver TLE8250GVIO is equipped with an under-voltage detection on the power supply VCC
and the power supply VIO. In case of an under-voltage event on VCC or VIO, the under-voltage detection changes
the operation mode of TLE8250GVIO to the Stand-By mode, regardless to the logical signal on the NEN pin (see
Figure 6).If the transceiver TLE8250GVIO recovers from the under-voltage event, the operation mode returns to
the programmed mode by the NEN pin.

1) Assuming the logical signal on the pin NEN keeps its values during the under-
voltage event. In this case NEN remains „Low“.
