3 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.
