RE46C108
Piezoelectric Horn Driver and 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
