The NJU72501 is a switching driver with multi mode charge pump
for piezo-sounder. It can drive outputs up to 18Vpp from 3V supply.
For adjusting the piezoelectric sounder sound volume, the charge
pump can operate in either of a 1x, 2x or 3x mode.
Because NJU72501 has the shutdown function, it is suitable for
the battery application.
