Abstract
A power switch module comprising a control component. Upon an indicated operating condition fulfilling a protection condition, the control component is arranged to transition the power switch module from an ON state to a latched-OFF state in which the control component is arranged to configure the switching device to be turned off to decouple the load node from the power supply node. Having transition to the latched-Off state, the control component is further arranged to determine whether a voltage level at the load node exceeds a threshold voltage level, and if it is determined that the voltage level at the load node exceeds the threshold voltage level, transition the power switch module from the latched-OFF state to a current-limited state in which the control component is arranged to control the switching device to limit current-flow there through.
