4.2
Two different modes of operation are available on the TLE7250GVIO. Each mode has specific characteristics in
terms of quiescent current or data transmission. The digital input pin NEN is used for mode selection.
illustrates the different mode changes depending on the status of the 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
switch to any mode of operation within the time period for mode change
