Texas Instruments  LED171596ARSLR

The LED171596A is a 96 channel matrix LED driver with independentchannel control, designed for driving locally dimmed displays. The device sports 4 low-resistancehigh side switches and 24 low side current sinks that can deliver up to 15 mA of continuous currentper channel. The driver has 9-bit duty cycle and 8-bit current control of each low-side LED currentsink.

Each current sink can be individually controlled through theI2C-compatible or SPI interface, but also has the capability to becontrolled with a single value through the global brightness control register. This globalbrightness control also passes through a brightness sloper function to create optically smoothbrightness transitions without the need for multiple register writes.
