Short-Circuit Protection While current-mode control offers a built-in means to shut off the MOSFET on a cycle-by-cycle basis, there is often a secondary protection mechanism.

Transistor VT2 provides short-circuit protection to the load, with red LED D4 indicting an overload. (D2 blows out simultaneously with an overload.) Short-circuit current does not exceed 38 mA.

According to the company, when combined with Breaktor circuit protection technology, which combines current switching and reconfigurable bi-directional short circuit protection with fast tripping ...
