SSL3250A
Photo flash dual LED driver
8.7.1 Addressing
Each SSL3250A in an I 2 C-bus system is activated by sending a valid address to the
device. The address always has to be sent as the first byte after the start condition in the
I 2 C-bus protocol Figure 14 .

Fig 14. I 2 C slave address
There is one address byte required since 7-bit addresses are used. The last bit of the
address byte is the read/write-bit and should always be set according to the required
operation. This 7-bit I 2 C address is 0110000b (30h). The 7-bit address plus the R/W bit
create an 8-bit write address of 60h and a read address of 61h.
The second byte sent to the SSL3250A is the subaddress of a specific register.
8.7.2 Data
After the subduers have been sent the data byte(s) are sent. The definition of the data
byte(s) is given in Figure 12 . After each data byte an acknowledge is given and the
subduers is automatically incremented to the next subduers.
A description of the data that can be programmed in the registers is given in the register
map in Section 8.7.3 .
