我把那段话摘抄下吧:
Pull-Low Resistor on the Gate Pin of MOSFET
in LD7575,an anti-floating resistor is implemented on the OUT pin to prevent the output from any uncertain state which may causes the MOSFET working abnormally or false triggered-on. However, such design won't cover the condition of disconnection of gate resistor Rg thus it is still strongly recommended to have a resistor connected on MOSFET gate terrminal to provide extra protection for fault condition.
