This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
V
OUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.

Notes:
1. Initiation supply voltage (VSI) is the supply voltage required to start the tone ringer oscillating.
2. Sustaining voltage (VSUS) is the supply voltage required to maintain oscillation.
3. VTR and ITR are the conditions applied to trigger in to start oscillation for VSUS≤VCC≤VSI.
4. VDIS and IDIS are the conditions applied to trigger in to inhibit oscillation for VSI≤VCC.
5. Trigger current must be limited to this value externally.

APPLICATION NOTE
The application circuit illustrates the use of the KK2410 devices in typical telephone or extension tone ringer application.
The AC ringer signal voltage appears across the TIP and RING inputs of the circuit and is attenuated by capacitor C1
and resistor R1.
C1 also provides isolation from DC voltages (48V) on the exchange line.
After full wave rectification by the bridge diode, the waveform is filtered by capacitor C4 to provide a DC supply for
the tone ringer chip.
As this voltage exceeds the initiation voltage (VSI), oscillation starts.
With the components shown, the ouptut frequency chops between 512(fh1) and 640Hz(fh2) at a 10Hz(fL) rate.
The loudspeaker load is coupled through a 1300Ω to 8Ω ransformer.
The output coupling capacitor C5 is required with transformer coupled loads.
When driving a piezo-ceramic transducer type load, the coupling C5 and transformer (1300Ω:8Ω) are not required.
However, a current limiting resistor is required.
The low frequency oscillator oscillates at a rate (fL) controlled by an external resistor (R2) and capacitor (C2).
The frequency can be determined using the relation fL=1/1.289R2xC2. The high frequency oscillates at a fH1, fH2
controlled by an external resistor (R3) and capacitor (C3). The frequency can be determined using the relation
fH1=1/1.504R3xC3, fH2=1/1.203R3xC3.
