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.

Features

  • Low quiescent current
  • Low horn driver Ron
  • Voltage regulation to 3.3V or 5V
  • -40°C to +85°C operating temperature range
  • Package options
    • DIP-8
    • SOIC-8
  • RoHS compliant and Pb-free

Applications

  • Smoke detectors
  • CO detectors
  • Personal security products
  • Electronic toys
