TYPICAL APPLICATIONS
SUPPLEMENTAL APPLICATION NOTES

DD1
output current deglitcher time:IDD1-DGLT: typ
55 μs
T2: Over current detected to SBC wake-up (INT pulse)
= typ 60 μs
The total time is 148 μs in this case.
LX with Cyclic Sense
Figure 33.
T1: Is dependent on the selected cyclic sense timing in
the TIM2 register (5 ms to 400 ms). LX is sampled 10 μs
before the end of cyclic sense on time. If the LX correct
wake-up level happens just after sample point, the
wake-up will be detected at the next HS1 activation and
a complete period is lost.
T2: It is the same than Lx to INT pulse: typ 100 μs
The total time is around 5.13 ms (for a cyclic sense total
time of 5 ms) in the above example.
