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.
