标题: RE46C104 DataSheet [打印本页] 作者: admin 时间: 2010-4-17 18:55 标题: RE46C104 DataSheet Piezoelectric Horn Driver and Voltage Converter
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.
