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), (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 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 kΩ 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)
