LOGIC INPUTS
Pins CONTROL, HALF/FULL, CLOCK, RESET and CW/CCW are TTL/CMOS and uC compatible logic inputs.
The internal structure is shown in Fig. 7. Typical value for turn-on and turn-off thresholds are respectively
V
th(ON)
= 1.8V and V
th(OFF)
= 1.3V.
Pin EN (Enable) has identical input structure with the exception that the drain of the Overcurrent and thermal
protection MOSFET is also connected to this pin. Due to this connection some care needs to be taken in driving
this pin. The EN input may be driven in one of two configurations as shown in Fig. 8 or 9. If driven by an open
drain (collector) structure, a pull-up resistor R
EN
and a capacitor C
EN
are connected as shown in Fig. 8. If the
driver is a standard Push-Pull structure the resistor R
EN
and the capacitor C
EN
are connected as shown in Fig.
9. 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. More information on selecting the values is found in the Overcurrent
Protection section.
