Note 3: An internal zener on the GATE n pins clamps the charge pump
voltage to a typical maximum operating voltage of 22V. External overdrive
of a GATE pin (for example, from capacitive coupling of V
beyond the internal zener voltage may damage the device. If a lower
GATE n pin clamp voltage is desired, use an external zener diode.
