16-channel low noise LED matrix manager with internal clock

The TPS92665 LED matrix manager device enables

fully dynamic adaptive lighting solutions by

providing individual pixel-level LED control. The

device includes four sub-strings of four series

connected integrated switches for bypassing

individual LEDs. The individual sub-strings allow

the device to accept either single or multiple

current sources.

The TPS92665 features an internal oscillator. The

internal oscillator can be shared to other system devices through the internal low

noise LVDS transmitter and receiver blocks. The multi-drop, universal, asynchronous,

receiver transmitter (UART) serial interface is compatible with TPS92664, TPS92667,

TPS92662x and TPS92663x devices. An on-board ADC with multiplexed inputs samples all

LED channels as well as IC die temperature. The ADC also samples dedicated ADC

inputs for use with system temperature compensation, LED binning and coding.

The TPS92665 incorporates registers for

programming phase shift and pulse width of each

individual LED in the string and for reporting LED

open, short faults and functional parameters.
