描述 Description

The TPS92667 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 TPS92667 has an internal low noise LVDS receiver input for a system clock provided by a TPS92664 or TPS92665 device. The multi-drop, universal, asynchronous, receiver transmitter (UART) serial interface is compatible with TPS92664, TPS92665, TPS92662x and TPS92663x devices.

The TPS92667 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.
