3 Description

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 multidrop,

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.
