Description
EVAL-L99PM62-72 is designed to evaluate the performance of two Power Management. The evaluation board comes pre-assembled with L99PM62GXP and L99PM72GXP ICs providing electronic control modules with enhanced power management functionality including various standby modes, as well as LIN and HS CAN physical communication layers. This Evaluation board consists of a motherboard (STM8 Universal Board) and two daughterboards. The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the devices assembled in two different daughterboards. With the aim to make the board usage and settings simpler, ST provides a dedicated user-friendly software with a Graphic User Interface (GUI). This enables the user to set L99PM62GXP and L99PM72GXP parameters and registers, simultaneously showing real time device diagnostic information like output current evolution, battery voltage monitoring, board temperature and much more.
