RE46C105
Piezoelectric Horn Driver with Voltage Regulator and LED Driver
Product Specification
General Description
The RE46C105 is a piezoelectric horn driver with a
voltage regulator and an open drain NMOS driver
suitable for use with a light emitting diode. It is
intended for 9V battery applications which require a
low voltage logic supply. The regulator can be
operated at either 3.3V or 5V. The horn feedback
control pin is designed for use with self-oscillating
piezoelectric horn but can also be used in direct
drive applications. A low battery detection circuit is
also provided.
Applications
Smoke detectors
CO Detectors
Personal Security Products
Electronic Toys

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to
the device. These are stress ratings only and operation at these conditions for extended periods
may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention
procedures should be used when handling this product. Damage can occur when exposed to
extremely high static electrical charges.
