The LED171596A is a 96 channel matrix LED driver with independent channel control, designed for driving locally dimmed displays. The device sports 4 low-resistance high side switches and 24 low side current sinks that can deliver up to 15 mA of continuous current per channel. The driver has 9-bit duty cycle and 8-bit current control of each low-side LED current sink.
Each current sink can be individually controlled through the I2C-compatible or SPI interface, but also has the capability to be controlled with a single value through the global brightness control register. This global brightness control also passes through a brightness sloper function to create optically smooth brightness transitions without the need for multiple register writes.
