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
