Abstract
A current determination circuit is configured to determine a state of current passing through a coil of a motor and includes a high side circuit, a low side circuit and a processor. The high side circuit is configured to output a first determination signal according to a first voltage between two ends of a first body diode of a high side transistor and the voltage level of a first control signal. The low side circuit is configured to output a second determination signal according to a second voltage between two ends of a second body diode of a low side transistor and the voltage level of a second control signal. The processor is configured to receive the first determination signal and the second determination signal and determine the state of current according to the voltage level of the first determination signal and the voltage level of the second determination signal.
