RE46C108
Piezoelectric Horn Driver with Voltage Regulator
Product Specification
General Description
The RE46C108 is a piezoelectric horn driver
with a voltage regulator that can operate at
3.3V or 5V. It is intended for applications
requiring a 9V horn driver with a low voltage
logic supply. The horn feedback control pin
is designed for use with self-oscillating
piezoelectric horn but can also be used in
direct drive applications.
Applications
Smoke detectors
CO Detectors
Personal Security Products
Electronic Toys
Features
• Low Quiescent Current
