TECHNICAL DATA
Telephone Tone Ringer with
Bridge Diode
IL6840
The IL6840 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 (fR) alternating
with a low frequency (fL) 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
