A driver circuit includes a primary driver sub-circuit, a comparator sub-circuit and an auxiliary driver sub-circuit. The primary driver sub-circuit is configured to (i) generate an output voltage, and (ii) supply a predetermined maximum amount of current from a power source to a load via a first switch. The comparator sub-circuit is configured to (i) detect when a high-power dissipation condition exists which could lead to overheating the primary driver sub-circuit, and (ii) based on detection of the condition, generate a first output signal. The auxiliary driver sub-circuit is configured to, based on the first output signal, transition between (i) pulling-up the output voltage to the source voltage and supplying current from the power source to the load, and (ii) decreasing an amount of current being supplied to the load.
