TYPICAL APPLICATIONS
SUPPLEMENTAL APPLICATION NOTES
LX Wakes up SBC from Sleep Mode
Below is the case where the SBC is in sleep mode and is awaked by LX positive edge.
Figure 26. SBC in Sleep Mode
T1 (LX high level to VDD1 turn on): typ 100 s.
T2: VDD1 rising time is dependent on the capacitor and the load connected to VDD1. It can be approximated by the capacitor
charging time with the regulator output current limitation: T2 = (C x U)/I. With C = 100 mF, IDD1 = 200 mA min., U = 5.0 V
so T2 = 2.5 ms).
T3 (VDD1>RST-TH (4.6 V by default) to reset high): parameter Rest dur: 4.0 ms max.
The total time is 6.6 ms in this example.
CAN Wake-up
The following case describes the signal for CAN wake-up. Refer to page 53 for more details on CAN wake-up signals and the
TCAN analysis.
Figure 27. CAN Wake-up
T1(third valid CAN dominant pulse to VDD1 turn on): typ 80 s.
T2 and T3 identical to page 42 above
The total time is 6.58 ms in this example.
LX with Cyclic Sense
The case below is a description of the wake-up by LX input associated with the cyclic sense function.
