HOW 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.
