14600
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. The MC14600
is easily configured with a minimum number of external components to serve a
wide range of applications and circuit configurations. Typical applications include
intrusion alarms, moisture or water ingress alarms, and personal safety devices.
Features
• High Impedance, FET Input Comparator
• Comparator Outputs for Low Battery and Alarm Detect
• Alarm Detect Threshold Easily Established with 2 Resistors
• 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
• Pb-Free Packaging Designated by Suffix Codes ED and EG
