RE46C101
Piezoelectric Horn Driver and LED Driver Circuit
Product Specification
General Description
This product is 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 design also provides an open drain N-
channel driver suitable for use with a light emitting
diode.
Applications
Smoke detectors
CO Detectors
Personal Security Products
Electronic Toys

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These
are stress ratings only and operation at these conditions for extended periods may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be
used when handling this product. Damage can occur when exposed to extremely high static electrical charge.
