Logic inputs
Pins INx and ENx are TTL/CMOS and microcontroller compatible logic inputs. The internal
structure is shown in
respectively 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
(collector) structure, a pull-up resistor R

are connected as shown in
2.2 kΩ to 180 kΩ. Recommended values for R
More information on selecting the values is found in the overcurrent protection section.
