STCS1A Detail description
11/19
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 V
DRAIN
pin. If V
DRAIN
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.
