It is important to remember that during the Turnon of the MOSFET the output current to the Gate is drawn from the V_CC supply pin. The V_CC pin must be bypassed with a capacitor with a value of at least ten times the Gate capacitance, and no less than 0.1 μF. If the V_CC supply must be taken negative with respect to ground, for example during a reverse battery condition, the current from the V_CC pin must be limited to 20 mA. The addition of a diode in series with the V_CC input is recommended. This diode drop does not subtract significantly from the charge pump gate overdrive output voltage.
