Piezoelectric Horn Driver and Voltage Converter
Product Specification General Description Features 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. Applications
