STEVAL-VNH5050A Evaluation board
Introduction
STEVAL-VNH5050A offers dedicated power stage and controls suitable for electric DC
motor driving. This evaluation board features the VNH5050A. It is an H-bridge belonging to
®
the VNH Motor Driver series based on VIPower
proprietary technology. Typical
applications are dual washer pump and seat regulation.
This evaluation board consists of a motherboard (STM8 Universal Board) and a daughter-
board. The motherboard, based on STM8 microcontroller, provides the logic section for
monitoring and driving the VNH5050A 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 VNH5050A parameters
(PWM, Motor direction...), while showing real time device diagnostic information, such as
current output evolution, battery voltage monitoring, board temperature and much more.
