ATA6622/ATA6624/ATA6626

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) results in a

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

Sleep Mode

A falling edge at EN when TXD is low switches the IC into Sleep Mode. The TXD Signal has to

be logic low during the Mode Select window (Figure 4-4 on page 10). In order to avoid any influ-

ence to the LIN-pin during switching into sleep mode it is possible to switch the EN up to 3.2 µs

earlier to LOW than the TXD. Therefore, the best and easiest way are two falling edges at TXD

and EN at the same time.The transmission path is disabled in Sleep Mode. The supply current

I_VSsleepfrom V_Battis typically 10 µA.
