Current state determination method and circuit
A current state determination method is configured to determine a state of current passing through a coil of a motor and includes: at a first time point when a high side transistor and a low side transistor are switched to a cut-off state, measuring a voltage of a node where the high side transistor...

| description | A current state determination method is configured to determine a state of current passing through a coil of a motor and includes: at a first time point when a high side transistor and a low side transistor are switched to a cut-off state, measuring a voltage of a node where the high side transistor, the low side transistor and the coil are coupled, so as to output a first voltage; at a second time point when the high side transistor and the low side transistor are maintained in the cut-off state, measuring the voltage of the node, so as to output a second voltage; comparing the first voltage and the second voltage to obtain a comparison result; and determining the state of the current according to the comparison result. The present disclosure also provides a current state determination circuit for performing the current state determination method. |
