The present invention relates to a circuit for driving an inductive load and, more particularly, to an inductive load driving circuit which maintains a balance with surge protection and over-current protection functions. An inductive load driving circuit according to an embodiment of the present invention comprises: a first switch for driving an inductive load; a pulse driving circuit for generating a pulse signal for driving the voltage of a gate node of the first switch; a first protection circuit for, when a surge occurs, limiting a drain-source voltage such that the drain-source voltage of the first switch does not exceed a breakdown voltage; and a balancing circuit for, when the surge occurs, separating the pulse driving circuit from operations of the first protection circuit and the first switch. |
