RE46C104
Piezoelectric Horn Driver and
Voltage Converter Product Specification
General Description
The RE46C104 is a piezoelectric horn driver with
voltage converter to provide maximum audibility in low
voltage applications.
The feedback control pin is designed for use with self-oscillating piezoelectric horn but can also be used in direct drive applications.
The built-in charge pump
voltage converter provides increased supply
voltage for the horn drivers allowing outputs to swing from Vss to 2 x Vdd.
A charge pump enable pin is provided to minimize supply current when not in use.
