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

Features

• Low Quiescent Current (<100na)

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.
