R&E International
A Subsidiary of Microchip Technology Inc. RE46C108
Piezoelectric Horn Driver and Voltage Regulator
Product Specification General Description Features 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 selfoscillating piezoelectric horn but can also be used in
direct drive applications. Applications
Smoke detectors
CO Detectors
