N ote 2 : Sustaining Supply Voltage (Vsus) is a supply voltage r equir ed to maintain oscillation of the tone ringer. N ote 3 : Oscillation fr equenc y is deter mined by the f ollowing equations (1),( 2) and (3) : (1) fL=1/1.234, R1, C1 (Hz) (2) fH1=1/1.515, R2, C 2 (H z) ( 3) fH2=1.24 fH1 (Hz) Method Of Using Rsl In the GP31002, using the RSL ter minal c an change the initiation supply curr ent (Isi). The r esistor R SL is c onnected to G nd fr om Pin 2 as s how in Fig. 3. Further, the initiation supply curr ent (Isi) c an be changing the value of RSL. Fig. 4 shows the gr aph of Vs-Is char acteristic at the time when RSL has been changed to thr ee values. The Vs-Is char acteristic at the time when RSL=6.8 k (the “L” level voltage is under 2V) c oincides with that at the time when Pin2 of the GP31002 has been us ed at an open state. If Pin 7 is c onnected to Gnd as shown in Fig. 5, the GP31002 c an stop oscillation. (UVLO) http://www.SeCoSGmbH.com/ Any changing of specification will not be informed individual 01-Jun-2002 Rev.
