Abstract
A driving circuit includes a power supply, an input capacitor, a Hall sensor, a first amplifier, a second amplifier, a full-bridge driver circuit, and a first operational amplifier. The input capacitor is coupled to the power supply. The input end of the first amplifier and the second amplifier is coupled to the output end of the Hall sensor. The control end of the full-bridge driver circuit is coupled to the output end of the first amplifier and the output end of the second amplifier. The first operational amplifier includes a first input end for receiving a first reference voltage and a second input end coupled to the first output end of the full-bridge driver circuit.
