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),(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) Method Of Using Rsl In the GP31002, using the RSL terminal can change the initiation supply current (Isi). The resistor RSL is connected to Gnd from Pin 2 as show in Fig. 3. Further, the initiation supply current (Isi) can be changing the value of RSL. Fig. 4 shows the graph of Vs-Is characteristic at the time when RSL has been changed to three values. The Vs-Is characteristic at the time when RSL=6.8 k coincides with that at the time when Pin2 of the GP31002 has been used at an open state. If Pin 7 is connected to Gnd as shown in Fig. 5, the GP31002 can stop oscillation. (the “L” level voltage is under 2V) (UVLO) http://www.SeCoSGmbH.com/ 01-Jun-2002 Rev.
