AFE4403: LED current temperature dependency

Part Number:AFE4403

Hi team,

I'm an FAE supporting some industrial customers in Japan.

My customer will employ AFE4403 for their product and provided some questions as follows.

Questions

1. Does LED setting current have temperature dependency?
   (Does AFE4403 have characteristics that accuracy of setting current deteriorates  or doesn't flow  at all via temperature?)
2. Does AFE4403 do feedback control internally for current setting?
   
   1. If so, could you please provide more detail?
      e.g. feedback value 
   2. If AFE4403 has condition for correct control, could you provide that?
      e.g. w/o photo-diode, AFE4403 can't control LED

I'm looking forward to hearing back from you.

Best regards,

Shota Mago
