TI TPS92665 LED Matrix Manager

TI TPS92665 LED Matrix Manager
TI's TPS92665 LED Matrix Manager enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control. The TPS92665 device includes four substrings of triple-series integrated switches for bypass connections to individual LEDs. Through individual substrings, the device can accept single or multiple current sources.
The TPS92665 has an internal oscillator. The internal oscillator can be shared with other system components through the internal low-noise LVDS transmitter and receiver blocks. Multidrop Universal Asynchronous Transceiver with serial interface compatible with TPS92664, TPS92667, TPS92662x and TPS92663x devices. On-board ADC with multiplexed inputs to sample all LED channels, IC die temperature. The ADC also samples dedicated ADC inputs for system temperature compensation, LED binning, and encoding.

The TI TPS92665 contains registers to program the phase shift and pulse width of each LED in the string, as well as to report LED open-circuit, short-circuit faults, and functional parameters.
