The TLE7269G has 3 major operation modes: • Stand-By mode • Normal Operation mode • Sleep mode The Normal Operation mode contains 3 sub-operation modes, which differentiate by the slew rate control of the LIN Bus signal (see Figure 4). ...
Page 10
Normal Slope Mode In Normal Slope mode data transmission rates kBauds are possible. Setting the EN pin to “High” starts the transition to Normal Operation mode. Depending on the signal on the TxD1 pin, the TLE7269G ...

Stand-By Mode The Stand-By mode is entered automatically after: • A Power-Up event on the supply • A bus Wake-Up event on pin BUS1 or pin BUS2. • A local Wake-Up event on the pin WK. • A power ...
Page 13
Sleep Mode In order to reduce the current consumption the TLE7269G offers a Sleep mode. In Sleep mode the quiescent V current on and the leakage current on the pins BUS1 and BUS2 are cut back to a minimum. ...
