Negative Voltage and Reverse Current
negative voltage occurring on Vbus pin, down to −28 V.
When a negative voltage occurs, the IN pins are
disconnected from Vbus pins . This negative protection is
available in all modes
Thermal Shutdown Protection
shutdown protection allows to open the internal MOSFET
in order to instantaneously decrease the device temperature.
