Sleep Mode
A falling edge at EN while TXD is low switches the IC into Sleep mode. The TXD Signal has to
be logic low during the Mode Select window (see Figure 4-4). We recommend using the same
microcontroller port for EN as for TXD; in this case the mode change is only one command.
In Sleep mode the transmission path is disabled. Supply current from V
Batt is typically
I
VSsleep =10A. The VCC regulator is switched off; NRES and RXD are low. The internal slave
termination between pin LIN and pin VS is disabled to minimize the power dissipation in case pin
LIN is short-circuited to GND. Only a weak pull-up current (typically 10 A) between pin LIN and
pin VS is present.
A falling edge at pin LIN followed by a dominant bus level maintained for a certain time period
(t
bus) results in a remote wake-up request. The device switches from Sleep mode to Pre-normal
mode. The V
CC regulator is activated and the internal LIN slave termination resistor is switched
on. The remote wake-up request is indicated by a low level at pin RXD to interrupt the microcon-
troller and a high level at pin TXD (see Figure 4-5 on page 9).
With EN high you can switch directly from Silent to Normal mode. In the application where the
ATA6620N supplies the microcontroller, the wake-up from Sleep mode is only possible via pin
LIN.
If the device is switched into Sleep mode, V
CC ramps down without generating an undervoltage
reset at pin NRES.
