| R&E International RE46C100 Piezoelectric Horn 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. Features * * * * * Low Quiescent Current (<100na) Low Driver Ron - 20 typical at 9V Wide Operating Voltage Range 8 Pin DIP and SO Packages Available in Standard Packaging or RoHS Compliant Pb Free Packaging Applications Smoke detectors CO Detectors Personal Security Products Electronic Toys Pin Configuration NC VDD NC FEED 1 2 3 4 8 7 6 5 HRNEN HORNS HORNB VSS ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Input Voltage Range Except FEED FEED Input Voltage Range Input Current except FEED Operating Temperature Storage Temperature Maximum Junction Temperature SYMBOL VDD Vin Vinfd Iin TA TSTG TJ VALUE 18 -.3 to Vdd +.3 -10 to +22 10 -40 to 85 -55 to 125 150 UNITS V V V mA C C C 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.
