... L6370 3.4 Short circuit operation In order to minimise the power dissipation when the output is shorted to grounded, an innovative, non dissipative short cicuit protection (patent pending) is implemented, avoiding, thus the intervention of the thermal protection in most cases. Whenever the output is shorted to ground, or, generally speaking, an over current is sinked by the load, the output devices is driven in linear mode, sourcing the Isc current (typically 3 ...
