TLC59116: 60 LED individual Flash control via I2C LM3565 LM3643 LM2754 TLC59116

Part Number: TLC59116
Other Parts Discussed in Thread: LM3643, LM3565, LM2754,

In a application I need to design, I would like to control 60 LEDs individually via i2c preferably in flash mode.

Drivers such as LM3565 LM3643 LM2754 that support flash can not driver more than 4 LEDs also there no option for configuring addreses, if used multiple of them.

Drivers such as TLC59116 have high channel count but do not have flash mode.

Can someone advise best approach for this problem?

Thanks in advance.

    Hello,

    The independent control of the flash drivers with a channel count up to 60 is not necessarily straightforward.  To get independent control you could use and I2C bus multiplexer such as the PCA9548A and connect multiple flash drivers I2C lines to the outputs.  Which flash features in particular are you needing?  Is it the high current or is it the protection and control mechanisms?
