Wake Up from Sleep/Silent Mode at an Insufficient Falling Edge at Pin LIN

If the ATA6620N is in Sleep mode or Silent mode and the voltage at the LIN Bus falls to a value

lower than VLINL < V_S– 3.3V (see “Electrical Characteristics” numbers 9.5 and 9.6) but higher

than 0.6 × V_S, then a wake up is detected and the circuit switches to pre-normal mode and the

internal NMOS- transistor connected to the pin TXD is switched on and pulls down the pin TXD

to Ground. The following figure shows the corresponding diagram for the wake-up from silent

mode. The wake-up process from Sleep mode works analogue to this.
