A dropping power supply
blocking of the LIN network by a local ECU the TLE8458Gx has an integrated Power - On reset at the supply
and an Under-Voltage detection at the supply
reset level
output stage of the TLE8458Gx is disabled and no communication to the LIN bus is possible. The internal bus
termination remains active as well as the
In Stand-By mode the RxD pin indicates the low power supply condition with a logical HIGH signal. Setting the EN
pin to logical HIGH changes the operation mode back to Normal Operation mode.
