When the thermal shutdown temperature is reached, the power stage is disabled and the EN\FAULT input is
forced low through the integrated open-drain MOSFET (refer to Figure 13. Thermal shutdown management).
The protection and the EN\FAULT output are released when the IC temperature returns below a safe operating
value (TjSD - TjSD,Hyst).
