Abstract
A load current is limited to a safe level with a current protection logic circuit within a first selected interval after detection of a fault condition. The current protection logic circuit returns the load current to a normal level within a second selected interval after correction of the fault condition, wherein said safe level is less than one half of the normal level. The current protection logic circuit is a feature of a high side driver comprising at least two source drivers, each source driver being configured to switch an electrical load to a common power supply, and comprising a respective current protection logic circuit.
