TLC5941: About Icc

Part Number:TLC5941

Hi,

I am doing motion verification.
If VCC (= 3.3 V) is turned on in the following condition, Icc of TLC 5941 may continue to flow near 80 mA.
I think that the current consumption is high, but what kind of cause can be considered?

(conditions)
R (IREF) = 866 Ω
SCLK, SIN, MODE = Low fixed
BLANK = Active (3.66 kHz)
GSCLK = Active (15 MHz)
VLED (8 V), all channel

Also, in the case of R (IREF) = 866 Ω in normal operation, how much is Icc(max)?

Best Regards,
