TPS92662-Monitor

The TPS92662 is a powerful high-brightness LED matrix manager for LED headlights. It enables efficient control and monitoring of LED arrays in modern vehicle lighting systems.

Configuration is carried out via UART, which is transmitted through a CAN transceiver, making it particularly robust against interference. Thanks to UART signal cascading, up to 32 TPS92662 chips can be connected together. Each chip can be addressed individually using device IDs or as a broadcast and finely configured through 139 registers per chip.

For easy use and analysis, we have developed a dedicated TPS92662 monitor. It allows simultaneous logging and configuration of UART channels. The monitor consists of a hardware adapter and a CANoe integration, significantly simplifying error diagnostics, monitoring, and control of the LED matrix.
