摘要： A circuit includes a switching module, a control module, and a driving module. The driving module is electrically coupled between the control module and the switching module for generating a driving signal. The driving module includes a normal driving unit and a fault protection unit. The normal driving unit is for turning on and off the switching module according to a first command signal from the control module. The fault protection unit is for lowering the driving signal from a driving value to a protection value according to a second command signal from the control module during a fault protection period after the control module receives a fault signal.
