UTC TA31002 LINEAR INTEGRATED CIRCUIT  
TELEPHONE TONE RINGER  
DESCRIPTION  
The UTC TA31002 is a bipolar integrated circuit  
designed for telephone bell replacement. It can also  
be used as alarms or other alerting devices.  
FEATURES  
*Current consumption is small. (at no-load)  
*Package is compaction. (DIP-8 pin)  
*Oscillation frequency is variable.  
*Built-in threshold circuits prevent false triggering due  
to power noise as well as “chirps” due to rotary dial.  
*Few external componens.

*NOTE :  
1. Initiation supply voltage (Vsi) is a supply voltage required to start oscillation of the tone ringer.  
2. Sustaining supply voltage (Vsus) is a supply voltage required to maintain oscillation of the tone ringer.  
3. Oscillation frequency is determined by the following equations 1,2,and 3.  
(1) fL=1/1.234•R1•C1 (Hz) ; (2)fH1=1/1.515•R2•C2 (Hz); (3)fH2=1.24 fH1(Hz)

APPLICATION NOTE  
In the TA31002 the initiation current consumption (Isi) can be changed by using the RSL terminal. The resistor  
RSL is connected to GND from PIN2 as shown in fig.1. Further, the initation current consumption(Isi) can be  
changed by changing the value of RSL.  
Fig.2 show the graph of Vs-Is characteristic at the time when RSL has been changed to three values. The Vs-Is  
characteristic in TA31002 at the time when RSL=6.8kΩ coincides with that at the time when PIN2 of the TA31001  
has been used at an open state.
