Overview
The TPS92664-Q1, produced by Texas Instruments, is a 16-channel low noise LED matrix manager designed for automotive applications. This device enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control. It features four sub-strings of four series-connected integrated switches, allowing the device to accept either single or multiple current sources. The TPS92664-Q1 includes an internal oscillator, which can be shared with other system devices through low noise LVDS transmitter and receiver blocks. It also supports multi-drop UART serial communication compatible with other TI LED matrix manager devices.
