AX31002
AX31002 Series
DIP-8 Package
Bipolar Tone Ringer IC
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

Note 1: Initiation Supply Voltage (Vsi) is a supply voltage required to start oscillation of the tone ringer.
Note 2: Sustaining Supply Voltage (Vsus) is a supply voltage required to maintain oscillation of the tone ringer.
Note 3: Oscillation frequency is determined by the following equations: (1) fL=1/1.234xR1xC1 (Hz) (2) fH1=1/1.515xR2xC2 (Hz) (3) fH2=1.24fH1 (Hz)
