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
