Logic inputs
Pins IN1A, IN2A, IN1B, IN2B, ENA and ENB are TTL/CMOS and microcontroller compatible
logic inputs. The internal structure is shown in Figure 6. Typical value for turn-on and turn-off
thresholds are respectively Vthon = 1.8 V and Vthoff = 1.3 V.
Pins ENA and ENB are commonly used to implement overcurrent and thermal protection by
connecting them respectively to the outputs OCDA and OCDB, which are open-drain
outputs. If that type of connection is chosen, some care needs to be taken in driving these
(collector) structure, a pull-up resistor REN and a capacitor CEN are connected as shown in
from 2.2 k
Ω to 180 kΩ. Recommended values for R
EN and CEN are respectively 100 kΩ and
5.6 nF. More information on selecting the values is found in the overcurrent protection
section.
