UM1689 User manual STEVAL-VNH5019A Evaluation board Introduction STEVAL-VNH5019A offers dedicated power stage and controls suitable for electric DC motor driving. This evaluation board features the VNH5019A. It is an H-bridge belonging to the VNH Motor Driver series based on VIPower® proprietary technology. Typical applications are window lift and seat regulation. This evaluation board consists of a motherboard (STM8 Universal Board) and a daughterboard. The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the VNH5019A assembled in the daughter-board. With the aim of simplifying board usage and settings, ST provides dedicated and user-friendly software including a Graphic User Interface (GUI). The GUI allows setting VNH5019A parameters (PWM, Motor direction…), while showing real time device diagnostic information, such as current output evolution, battery voltage monitoring, board temperature and much more.
