4.1  
4.2  
Normal Mode  
Silent Mode  
This is the normal transmitting and receiving mode. The voltage regulator is in Normal Mode and  
can source 50 mA. The undervoltage detection is activated. The watchdog needs a trigger sig-  
nal from NTRIG to avoid resets at NRES. If NRES is switched to low, the IC changes state to  
Fail-safe Mode.  
A falling edge at EN when TXD is high switches the IC into Silent Mode. The TXD Signal has to  
be logic high during the Mode Select window (see Figure 4-2 on page 8). The transmission path  
is disabled in Silent Mode. The overall supply current from VBatt is a combination of the IVSsi  
57 µA plus the VCC regulator output current IVCC  
.
The 3.3V/5V regulator with a 2% tolerance can source up to 50 mA. The internal slave termina-  
tion between the LIN pin and the VS pin is disabled in Silent Mode to minimize the power  
dissipation in the event that the LIN pin is short-circuited to GND. Only a weak pull-up current  
(typically 10 µA) between the LIN pin and the VS pin is present. Silent Mode can be activated  
independently from the actual level on the LIN, WAKE, or KL_15 pins. If an undervoltage condi-  
tion occurs, the NRES is switched to low, and the IC changes its state to Fail-safe Mode.
