UTCTA31002 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.

UTCTA31002 LINEAR INTEGRATED CIRCUIT
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=6.8kcoincides with that at the time when PIN2 of the TA31001 has
been used at an open state.
