    摘要： A power tool and a control method, the power tool including: a functional component, a motor, a power supply module, a controller and a drive circuit including: a first drive terminal and a second drive terminal respectively electrically connected to a first power terminal and a second power terminal of the power supply module; multiple high-side switches, high-side terminals of the high-side switches being respectively electrically connected to the first drive terminal; and multiple low-side switches, low-side terminals of the low-side switches being respectively electrically connected to the second drive terminal. The controller is configured to: output a first control signal to one high-side switch to make it in an on or off state; and output a second control signal to one low-side switch to make it in the other state; wherein the low-side terminal of one high-side switch is connected to the high-side terminal of one low-side switch.
