Logic inputs
Pins INx and ENx are TTL/CMOS and microcontroller compatible logic inputs. The internal
structure is shown in Figure 7. Typical value for turn-on and turn-off thresholds are
respectively V
th(ON)= 1.8 V and Vth(OFF)= 1.3 V.
Pin DIAG-EN 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 Figure 8 or Figure 9. If driven by an open drain
(collector) structure, a pull-up resistor REN and a capacitor CEN are connected as shown in
Figure 8. If the driver is a standard Push-Pull structure the resistor R
EN and the capacitor CEN
are connected as shown in Figure 9. The resistor R
EN should be chosen in the range from
2.2 k
Ω to 180 kΩ. Recommended values for R
EN and CEN are respectively 10 kΩ and 5.6 nF.
More information on selecting the values is found in the overcurrent protection section.
