The internal structure is shown in
are respectively Vthon = 1.8 V and Vthoff = 1.3 V.
Pins EN
Overcurrent and thermal protection MOSFETs (one for the bridge A and one for the
bridge B) are also connected to these pins. Due to these connections some care needs to
be taken in driving these pins. The EN
