Abstract
The present disclosure provides a control logic circuit. The control logic circuit controls an inverter circuit connected to a motor based on Hall signal. The control logic circuit generates an energization pattern for a compulsory synchronous drive, and switches between a high detection period and a low detection period in accordance with the energization pattern. The control logic circuit sets an internal Hall signal as high when a high level of the Hall signal is detected during the high detection period and sets the internal Hall signal as low when a low level of the Hall signal is detected during the low detection period. Therefore, the control logic circuit generates an FG signal according to the internal hall signal.
