Abstract
A drive circuit (10) and an electrical apparatus (100) are disclosed. The drive circuit (10) includes a driving module (11) which is connected to a driving end of an active fuse (20) and configured to provide a constant current and a constant voltage. The active fuse (20) blows under the driving of the constant current, and is conducted under the driving of the constant voltage. The problems in related technologies of switching devices (Q2, Q3) being prone to burning out or erroneous detection of the status of the active fuse (20) can be solved.
