Microchip Technology RE46C108 Piezoelectric Horn Driver

Microchip Technology RE46C108 is a Piezoelectric Horn Driver with an integrated voltage regulator, enabling it to operate at 3.3V or 5.0V. The RE46C108 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.
