Sleep Mode
Figure 3-4.
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
influence to the LIN-pin during switching into sleep mode it is possible to switch the EN up to
3.2µs 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
The VCC regulator is switched off. NRES and RXD are low. The internal slave termination
between the LIN pin and VS pin is disabled, only a weak pull-up current (typically 10µA)
between the LIN pin and the VS pin is present. Sleep Mode can be activated independently
from the current level on the LIN, WAKE, or KL_15 pin.
A voltage less than the LIN Pre_Wake detection VLINL at the LIN pin activates the internal LIN
receiver and switches on the internal slave termination between the LIN pin and the V
