Notes:
(1) ΔV
(2) Once tripped, flash output will remain disabled until FLEN pin is cycled or reset via serial interface.
(3) Current matching equals ± [I
- I
] / [I
+ I
].
(4) Test voltage is V
= 4.0V — a relatively extreme LED voltage — to force a transition during test. Typically V
OUT
= 3.2V for white LEDs.
(5) Guaranteed by design
is the voltage difference between any two LEDs.
