If however, the power is turned off or the chip is disabled, the internal circuit of the pin 1 will be opened.
In this way, the voltage at the capacitor C4 will be discharged through the resistor R4 and triggers the dual MOSFET turned on.

12. Protector
UVLO (Under voltage lockout)
The protector shuts down internal bias by the function of UVLO when the power supply voltage drops below 6V (min).
TSD (Thermal shutdown)
It shuts down the driver in case the chip temperature should rise upto 150
°
C by the function of thermal shutdown (TSD)
