S1T2418G01 General Description

The S1T2418G01/D02 is a monolithic integrated circuit telephone tone ringer with bridge diode. When coupled with an appropriate transducer, it replaces the electro-mechanical bell.

This device is designed for use with either a piezo transducer or an inexpensive transformer-coupled speaker to produce a pleasing tone composed of high frequencies (fH1, fH2) alternating with a low frequency (fS) 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 cannot affect correct operation of the device.

S1T2418G01 Maximum Ratings

Characteristic	Symbol	Value	Unit
Calling Voltage (f = 50Hz) Continuous Calling Voltage (f = 50Hz)	V_C	120	V_RMS
5 sec ON / 10 sec OFF	I_C(ON-OFF)	200	V_RMS
Supply Current	I_CC	22	mA
Operating Temperature	T_OPR	-20 ~ +70
Storage Temperature	T_STG	-65 ~ +150

NOTE: Absolute maximum ratings are those values beyond which permanent damage to the device may occur. These are stress ratings only and functional operation of the device at or beyond them is not implied. Long exposure to these conditions may affect device reliability.

S1T2418G01 Features

• Built-in full wave bridge diode rectifier
• Low current consumption, in order to allow the parallel operation of 4 devices
• Few external components
• Tone and adjustable switching frequencies by external components
• High noise immunity to current hysteresis due to built-in voltage
• Adjustable activation voltage
• Internal zener diodes to protect against over-voltages
• Adjustable ringer impedance with external components

S1T2418G01 Typical Application

• Electronic telephone ringers
• Extension ringers
