Figure 20 shows the Overcurrent Detection operation. The Disable Time t
DISABLE
before recovering normal oper-
ation can be easily programmed by means of the accurate thresholds of the logic inputs. It is affected whether by
C
EN
and R
EN
values and its magnitude is reported in Figure 21. The Delay Time t
DELAY
before turning off the
bridge when an overcurrent has been detected depends only by C
EN
value. Its magnitude is reported in Figure 22.
C
EN
is also used for providing immunity to pin EN against fast transient noises. Therefore the value of C
EN
should be chosen as big as possible according to the maximum tolerable Delay Time and the R
EN
value should
be chosen according to the desired Disable Time.
The resistor R
EN
should be chosen in the range from 2.2K
to 180K
. Recommended values for R
EN
and C
EN
are respectively 100K
and 5.6nF that allow obtaining 200
μ
s Disable Time.
