Hi Team,

The customer does not want to use the single LED short function.

Q1. Can I open (FLOATING) the FAULT_S PIN when using the output 3CH integrated?

Q2. Can you detect DRIVER IC failure when LED STRING SHORT occurs?

Hi Frank,

B1, B2, B3 is High Current Chip Bead.

Can I still detect a short circuit in the LED string by opening FAULT_SPIN?

Fault_s pin is only used to detect single LED short fault.
