LED Current Setting
On the CAT400XA, the full scale LED current is set by the
external resistor connected between the RSET pin and
ground. Table 5 lists standard resistor values for several
LED current settings.

When the EN/DIM is initially taken high, the CAT400XA
becomes enabled and the LED channel current is set to the
full scale current according to the resistor RSET.
