Flyback current
Turning off the low side driver with an inductive load, its output voltage rises due to the
inductor that tries to drive current. This voltage is internally clamped by the flyback circuit at

The output current is determinated by the output characteristic and its voltage depends on
load resistance. In this mode, high power is dissipated in the output stage and its
temperature increases rapidly. When the output stage temperature exceeds the thermal
