The whole circuit includes Dynamic Self-Supply (DSS) circuit, over current protection circuit and temperature shutdowncircuit.
并具有动态自供电、过流保护、过温保护等功能。

If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdowncircuit takes over preventing the IC from overheating.
如果内部功耗变得太大，热量高沉没的规定外，热关断电路采用了防止芯片过热。
3
Internal circuit protection includes: thermal shutdown with hysteresis, UVLO, and crossover-current protection.
