I am implementing an LED design where I need a separate HW control line to gate a subset of LEDs being driven by the LP5860. I am thinking of using a low side FET as a switch but I am not sure if this will impact upside or downside deghosting features. 99% of the time, the _EN signal will be asserted so I don't think the case where _EN is toggling is critical.
Below is a snippet of my schematic showing how I intend to do the gating. Would the gating method here be appropriate? Would the deghosting features be impacted?
_EN is 5V logic. VLED is 5V. VCC is 3.3V
