RE46C107
DC to DC Converter, Voltage Regulator and Piezoelectric Horn Driver
Product Specification
General Description
The RE46C107 is intended for use in 3V or 4.5V
battery or battery-backed applications. The circuit
features a DC-to-DC up-converter and driver circuit
suitable for driving a piezoelectric horn. A selectable
3.0V or 3.3V regulator is also provided for
microprocessor voltage regulation. An LED driver
and low battery detection and signaling are also
available.
