V DD must be lowered to 0.2 V in order to reset part.
V DD(DRV)FET and V drv(LED) voltages are independent, but V drv(LED) ≤ V DD(DRV)FET at all times.
Each bit must be limited to a maximum of 100 mA and the total package limited to 1600 mA due to internal busing limits.

t VD;ACK = time for Acknowledgement signal from SCL LOW to SDA (out) LOW.
t VD;DAT = minimum time for SDA data out to be valid following SCL LOW.
A master device must internally provide a hold time of at least 300 ns for the SDA signal (refer to the V IL of the SCL signal) in order to
bridge the unde?ned region of SCL’s falling edge.
