METHOD FOR CONTROLLING MOTOR DRIVE CIRCUIT, AND MOTOR DRIVE CIRCUIT

WIPO Patent Application WO/2014/125604

A1

A motor drive circuit comprises: a CPU for controlling the operation of a bridge circuit by controlling the control voltage output from a pre-driver; a voltage detection circuit for detecting the voltage of a battery on the basis of the voltage of a first battery terminal; a power supply circuit for supplying the CPU with battery power input through a first switch terminal to start up the CPU in response to the turn-on of a main switch; and a first input circuit for outputting switch information to the CPU indicating whether or not a starter switch is turned on based on the signal from a second switch terminal. Further, the motor drive circuit calculates a limited motor-drive time and a prohibited motor-drive time on the basis of the battery voltage, and suspends the energization of the bridge circuit on determining that the limited motor-drive time has passed from the start of the energization of the bridge circuit when detecting the stoppage of rotation of the motor.
