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.
