Telephone Tone Ringer with
Bridge Diode
The IL2418 is a monolithic integrated circuit telephone tone ringer with
bridge diode, when coupled with an appropriate transducer, it replaces
the electro-mechanical bell. The device is designed for use with either
a piezo transducer or an inexpensive transformer coupled speaker to
produce a pleasing tone composed of a high frequency (f
R
) alternating
with a low frequency (f
L
) resulting in a warble frequency. The supply
voltage is obtained from the AC ring signal and the circuit is designed
so that noise on the line or variation of the ringing signal can not
affect correct operation of the device.
On chip high voltage full wave diode bridge rectifier
Low current consumption, in order to allow the parallel operation
of the 4 devices
Low external component count
Tone and switching frequencies adjustable by external
components
High noise immunity due to built-in voltage-current hysteresis
Activation voltage adjustable
Internal zener diodes to protect against over voltages
Ringer impedance adjustable with external components
