In total you can use up to 11 LITIX™ BASIC+ LED driver devices for one function on the same ERRN bus.

Rationale:

Referring to the ECs (Electrical Characteristics) "internal supply and EN pin" two parameters are of interest:


  • IS(fault,ERRN): Current consumption during fault condition triggered from another device sharing ERRN bus (all channels deactivated) is < 0.85 mA
  • IS(fault,OUT) Current consumption during fault condition (all channels deactivated) is < 1.25mA


So in total you can use 11 devices in one function since 1.25mA+(11-1)*0.85mA=9.75mA<10mA.

Find the datasheets and application notes at the LITIX Basic+ page.
