Logic inputs
Pins FWD/REV, BRAKE, EN, H1, H2 and H3 are TTL/CMOS and µC compatible logic
inputs. The internal structure is shown in
thresholds are respectively V
Pin EN (enable) may be used to implement overcurrent and thermal protection by
connecting it to the open collector DIAG output. If the protection and an external disable
function are both desired, the appropriate connection must be implemented. When the
external signal is from an open collector output, the circuit in
external circuits that are push-pull outputs the circuit in
R
and C
be found in
Figure 6.

EN
should be chosen in the range from 2.2 kΩ to 180 kΩ. Recommended values for R
EN
are respectively 100 kΩ and 5.6 nF. More information for selecting the values can
