Notes:

(1) Once tripped, flash output will remain disabled until FLEN pin is cycled or reset via serial interface.

(2) Test voltage is V

OUT

= 4.5V — a relatively extreme LED voltage — to force a transition during test. Typically V

OUT

= 3.3V for the white LED at

100mA.

(3) Guaranteed by design
