COIL DRIVER IC HAVING CIRCUIT CAPABLE OF CHANGING OUTPUT TERMINAL CONNECTED TO COIL INTO FLOATING STATE

摘要

The present invention relates to a coil driver integrated circuit (IC) capable of cutting off a connection state with a coil commonly connected to a plurality of output terminals of a coil driver IC by changing the output terminal connected to the coil into a floating state. The coil driver IC having a first output terminal and a second output terminal configured to be connected to one end and the other end of the coil comprises: a first switch connected to the first output terminal; a second switch connected to the second output terminal; a current driving unit including a first current terminal connected to the first output terminal via the first switch and a second current terminal connected to the second output terminal via the second switch; and a gate driving unit to control the first switch and the second switch to be an on state when driving the coil using a current provided from the first current terminal or the second current terminal and to control the first switch and the second switch to be an off state when not driving the coil.
