Application Note
Pin 2 allows connection of an external resistor RSL, which is used to program the solpe of the supply current vs
supply voltage characteristics (see Fig2), and hence the supply current up to the initiation voltage ( VSI ). This
initiation voltage remains constant independent of RSL.
The supply current drawn prior to triggering varies inversely with RSL, decreasing for increasing value of
resistance. Thus, increasing the value of RSL will decrease the amount of AC ringing current required to trigger the
device. As such, longer sucribser loops are possible since less voltage is dropped per unit length of loop wire due to
the lower current level. RSL can also be used to compensated for smaller AC couplin capacitors (C5 on Fig 3)
(higher impedance) to the line which can be used to alter the ringer equivalence number of a tone ringer circuit.
The graph in Fig2 illustrates the variation of supply current with supply voltage. Three curves are drawn to show
the variation of initiation current with RSL. Curve B( RSL=6.8KW) shows the I-V characteristic for the TS2411 tone
ringer.
Curve A is a plot with RSL<6.8KW and shows an increase in the current drawn up to the initiation voltage VSI. The
I-V characteristic after initiation remains unchanged. Curve C illustrates the effect of increasing RSL above 6.8KW
initiation current decreases but again current after triggering is unchanged.
