*Operating Voltage
: 2.3 to 5.0V(1x/ 2x Mode), 2.3 to 3.4V(3x Mode)
*Consumption current (Active) : IDS=0.3mA typ. (VIN=3V, DIN=4kHz, CPIEZO=15nF, 1x Mode)
(S.
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.
