RE46C100
Piezoelectric Horn Driver Circuit
Features:
• Low Quiescent Current (< 100 nA)
• Low Driver RON – 20typical 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.
