I would like to confirm the short/open detection of TLC5927-Q1.
1. In the datasheet, there is the specification of the open detection (IOUT,th).
I don't know 0.5*Itarget (%). If Itarget is 87.5mA, how do I caluculate it?
(0.5 * 87.5mA = 43.7mA or 0,5% 87.5mA = 0.437mA, ???)
2. The customer will make 350mA * 4 strings. They can relize the connection 4ch (87.5mA/ch) at anode of LED, I confirmed this e2e.
In this case, can TLC5927-Q1 keep the variation of the current 350mA +/- 10%?
3. When Iout is 87.5mA, they need set the cathode voltage (Vo) = LED VF + 1.0V.
Is this correct?
Best regards,
