Figure 20 shows the Overcurrent Detection operation. The Disable Time t
ation can be easily programmed by means of the accurate thresholds of the logic inputs. It is affected whether by
C
bridge when an overcurrent has been detected depends only by C
C
should be chosen as big as possible according to the maximum tolerable Delay Time and the R
be chosen according to the desired Disable Time.
