Abstract
A load driving device includes a driving switching element, an interrupting part, a short-circuiting switching element, and a protecting element. The driving switching element drives a load by controlling energization to the load. The interrupting part is disposed on an energizing path to the load. The interrupting part is not melted by a driving current to the load and is melted by an interrupting current larger than the driving current so as to interrupt energization to the load. The short-circuiting switching element is connected in parallel with the load and applies the interrupting current to the interrupting part. The protecting element protects the short-circuiting switching element.
