Texas Instruments TPS92665 LED Matrix Manager

Texas Instruments TPS92665 LED Matrix Manager 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 with 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 onboard ADC with multiplexed inputs samples all LED channels and IC die temperature. The ADC also samples dedicated ADC inputs for use with system temperature compensation, LED binning, and coding.

The Texas Instruments 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.
