Tone Ringer For Telephone Set
HO W TO USE THE RSL PIN
In the IC, the supply initiation current (lsi) can be
changed using the RSL Pin . As show is the diagram, the
RSL (Pin 2) is grounded through resistor Rs. By changing
the Rs value, supply initiation current can be changed.
Supply voltage (Vcc) vs. supply current (lcc)
characteristics resulting from changes in the value of Rs are
shown in the following diagram.
