1 / 8 page R&E International A Subsidiary of Microchip Technology Inc. RE46C126 CMOS Ionization Smoke Detector ASIC with Interconnect Product Specification © 2009 Microchip Technology Inc. DS22170A-page 1 General Description The RE46C126 is low power CMOS ionization type smoke detector IC. With few external components this circuit will provide all the required features for an ionization type smoke detector. An internal oscillator strobes power to the smoke detection circuitry for 10.5mS every 1.66 seconds to keep standby current to a minimum. A check for a low battery condition is performed every 40 seconds when in standby. . A 2/3 duty cycle continuous horn pattern is used for the alarm condition. An interconnect pin allows multiple detectors to be connected such that when one unit alarms all units will sound. Although this device was designed for smoke detection utilizing an ionization chamber it can be used in a variety of security applications. Utilizing low power CMOS technology the RE46C126 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268. Features • Guard Outputs for Ion Detector Input • +/-0.75pA Detect Input Current • Internal Reverse Battery Protection • Internal Low Battery Detection • Low Quiescent Current Consumption (<6.5uA) • Available in 16L PDIP or 16L N SOIC • ESD Protection on all Pins • Interconnect up to 40 Detectors • Compatible with MC14468 • Available in Standard Packaging or RoHS Complaint Pb Free Packaging Pin Configuration 16 1 GUARD2 DETCOMP 2 DETECT IO 15 3 GUARD1 LBADJ 14 4 VSEN STROBE 13 ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL VALUE UNITS Supply Voltage VDD 15 V Input Voltage Range Except FEED, IO Vin -.3 to Vdd +.3 V FEED Input Voltage Range Vinfd -10 to +22 V IO Input Voltage Range Vio1 -.3 to 17 V Reverse Battery Time TRB 5 S Input Current except FEED Iin 10 mA Operating Temperature TA -10 to 60 °C Storage Temperature TSTG -55 to 125 °C Maximum Junction Temperature TJ 150 °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 OSCAP 5 12 LED VDD RBIAS FEED 6 HS 11 7 HB 10 VSS 8 9 |
