Notice: The drive current of GATE pin is a variable value, which is decided by
I = K (VVDD − VGATE − 2.8)2 (Among these, K is a invariable coefficient，VGATE is the voltage of GATE pin, VVDD is
the voltage of VDD pin)；So the higher the VDD voltage is and the lower the output voltage is, the bigger the drive
transient current is. When the GATE voltage is 0V and the VDD voltage is 13V, the output drive current would over
120mA. The output driver current would decrease with increasing of the GATE voltage.
