Abstract
A motor drive control device includes a control circuit generating a drive control signal, and a drive circuit driving a motor. The drive circuit includes a plurality of switching legs each including a high-side transistor and a low-side transistor connected in series between a power line and a ground potential, and pull-up resistors each connected between the power line and a control electrode of the low-side transistor. The control circuit performs brake control to generate a drive control signal for turning off the high-side transistor and periodically switching the low-side transistor, when detecting a power supply voltage to be lower than a threshold voltage.
