Abstract
In a driving switching system, an H-bridge circuit includes a first P-type MOSFET, a first N-type MOSFET, a second P-type MOSFET and a second N-type MOSFET. The first N-type MOSFET connects to the first P-type MOSFET so as to have a first connection terminal. The second N-type MOSFET connects to the second P-type MOSFET so as to have a second connection terminal, wherein the first connection terminal and the second connection terminal are connected to a coil. A first and a second kickback voltage detection module respectively detect a first kickback voltage at the first connection terminal and a second kickback voltage at the second connection terminal. In the accompanying method, a first and a second driving module are selectively used to switch the first and second P-type MOSFET and the first and second N-type MOSFET once the first and second kickback voltages reach a first or a second threshold voltage.
