Datasheet - Detailed Description
Figure 19. Wake Up Signal Flowchart
Figure 21 shows the behavior of the wake up signal. The wake up signal will be low for t
wakeup
 = 10us. After that, the wake up signal will go to tri-
state condition. In case of an angle comparison with a result below the threshold, the signal will remain in tri-state condition. After switching on
VDD, the system needs max. 250us to generate an angle with maximum accuracy. A WAKE signal cannot be expected until the end of this
period.
WAKE Interface. An open drain NMOS structure is used in the WAKE pad. In order to generate a clear output signal level, a pull up resistor is 
required. The pad can drive 4mA.
