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