Abstract
A motor drive control device driving a motor having a first system coil and a second system coil, the motor drive control device comprising: a first drive circuit controlling energization of the first system coil; a second drive circuit controlling energization of the second system coil; a first temperature sensor detecting a temperature of the first drive circuit; a second temperature sensor detecting a temperature of the second drive circuit; and a signal output circuit outputting an output signal concerning whether or not any one of the first system coil and the second system coil is in an open state, based on a detection result by the first temperature sensor and a detection result by the second temperature sensor.
