Pull-Low Resistor on the Gate Pin of MOSFET
The LD7576X series consist with an anti-floating resistor on
the OUT pin to protect the output from abnormally operation
or false triggering of MOSFET. Even so, we still recommend
adding an external one on the MOSFET gate terminal to
provide more protection in case of disconnection of gate
resistor R
In such single-fault condition, as show in figure 22, the
resistor R8 can provide a discharge path to avoid the
MOSFET from being false-triggered by the current through
the gate-to-drain capacitor C
is always pulled low and placed in the off-state whenever
the gate resistor is disconnected or opened in any case.
