Low-Power CMOS
ALARM 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. 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.
