Logic inputs
Pins FWD/REV, BRAKE, EN, H1, H2 and H3 are TTL/CMOS and microcontroller compatible
logic inputs. The internal structure is shown in
thresholds are respectively V
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
