STMicroelectronics EVAL-L99UDL01 Evaluation Board

STMicroelectronics EVAL-L99UDL01 Evaluation Board demonstrates the centralized control of all the locks in a car using the L99UDL01 IC. This evaluation board incorporates a motherboard and a daughterboard. The motherboard is based on the SPC560B54 microcontroller that offers the logic section for monitoring and driving the L99UDL01 device on the daughterboard. This STMicroelectronics evaluation board is configurable through a dedicated user-friendly software with a GUI. The GUI enables to set the L99UDL01 control parameters and also shows the real-time diagnostics information as the current output and battery voltage monitoring. The EVAL-L99UDL01 board employs broad reverse battery protection with STD95N4F3 power MOSFET.
