Low–Power CMOS ALAEM IC with Horn Driver
The MC14600 Alarm IC is designed to simplify the process of interfacing an alarm level voltage condition to a piezoelectric horn and/or LED. With an extremely low average current requirement and an integrated low battery detect feature, the part is ideally suited to battery operated applications.
• High Impedance, FET Input Comparator
• Comparator Outputs for Low Battery and Alarm Detect
• Alarm Detect Threshold Easily Established with 2 Resistor
• Integrated Oscillator and Piezoelectric Horn Driver
• Low Battery Trip Point Set Internally (Altered Externally)
• Horn “Chirp’’ During Low Battery Condition
• Pulsed LED Drive Output
• Reverse Battery Protection
• Input Protection Diodes on the Detect Input
• Average Supply Current: 9 µA
