TPS92667-Q1 Automotive LED Matrix Manager
Texas Instruments' low-noise 16-channel manager features advanced diagnostics and is AEC-Q100-qualified for automotive applications
Texas Instruments' TPS92667 is a LED matrix manager that enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control. The device includes four substrings of four series-connected integrated switches for bypassing individual LEDs. The individual substrings allow the device to accept single or multiple current sources.
The TPS92667 has an internal low-noise LVDS receiver input for a system clock provided by the TPS92664 or TPS92665 device. The multi-drop, universal, asynchronous, receiver transmitter (UART) serial interface is compatible with the TPS92664, TPS92665, TPS92662x, and TPS92663x devices. The matrix manager incorporates registers for programming the phase shift and pulse width of each LED in the string and reports LED open, short faults, and functional parameters.
