RE46C100
Piezoelectric Horn Driver Circuit
Features:
• Low Quiescent Current (< 100 nA)
• Low Driver RON – 20typical at 9V
• Wide Operating Voltage Range
• Available in 8-pin DFN, PDIP and SOIC packages
General Description:
The RE46C100 devices are intended for applications
using a self oscillating piezoelectric horn, although it
can be used in direct drive applications. Feedback
control and a driver circuit are provided, as well as a
horn enable function.
The RE46C100 is intended for use in smoke detectors,
CO detectors, personal security products and
electronic toys.

Pb-free JEDEC designator for Matte Tin (Sn)
This package is Pb-free. The Pb-free JEDEC designator ( e3 )
can be found on the outer packaging for this package.
Note: In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line, thus limiting the number of available
characters for customer-specific information.
