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) : Method Of Using Rsl In the H31002P, using the RSL terminal can change the initiation supply current (Isi). The resistor RSL is connected to Gnd from Pin 2 as shown 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 Ω coincides with that at the time when Pin 2 of the H31002P has been used at an open state. If Pin 7 is connected to Gnd as shown in Fig. 5, the H31002P can stop oscillation. (the “L” level voltage is under 2V) C u r r e n t C o n s u p m p t i o n ( m A ) | V s u s V s i 0 1 02 03 0 S u p p l y V o l t a g e ( v ) Fig.4 Fig.5 Internal IC Pin 7 HF1 Fig.3 H31002P 5RSL Gnd Vs
