: 1/5 AX31002 Bipolar Tone Ringer IC AX31002 Series Description The AX31002 is a bipolar integrated circuit.
It is designed for telephone bell replacement.
It can also be used as alarms or other alerting devices.
Features • Current consumption is small • Oscillation frequency is variable • Adjustable start-up current • Higher driving capability • Built-in threshold circuits prevent false triggering due to power noise as well as 'chirps' due to rotary dial • Few external components • Easy connection to telephone system Applications • Telecom Tone Ringer Set Pin Connections 8 7 6 5 Pin1: VCC Pin2: RSL Trigger In (RSL) Pin3: Low Freq.
