STCS1A
Detail description
7.4
Diagnostic
When STCS1A is in on mode (EN is high), the device is able to detect disconnection or fail
of the LED string monitoring VDRAIN pin. If VDRAIN is lower than 75 mV the DISC pin is
pulled low regardless the PWM pin status. This information can be used by the system to
inform that some problem happens in the LEDs.
