ATA6622/ATA6624/ATA6626

A voltage less than the LIN Pre_Wake detection VLINL at the LIN pin activates the internal LIN

receiver.

Figure 4-2. Switch to Silent Mode

A falling edge at the LIN pin followed by a dominant bus level maintained for a certain time

period (t

bus

) and the following rising edge at the LIN pin (see Figure 4-3 on page 9) result in a

remote wake-up request. The device switches from Silent Mode to Fail-safe Mode. The internal

LIN slave termination resistor is switched on. The remote wake-up request is indicated by a low

level at the RXD pin to interrupt the microcontroller (see Figure 4-3 on page 9). EN high can be

used to switch directly to Normal Mode.
