4.2
Three different modes of operation are available on the TLE7250G. Each mode has specific characteristics in
terms of quiescent current or data transmission. NEN and NRM are used as the digital input pins for mode
selection.
supplying
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
