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.

1 Hardware description and setup
This section provides a description of the main components of this evaluation kit, giving
instruction for a quick setup of the motor control system.
1.1 Components description
The evaluation kit consists of two main components:
•Mother board based on STM8A microcontroller, interfacing host PC with H-Bridge
controller. The communication with the PC is established through isolated USB.
•Daughter Board assembling VNH5050A and the reverse battery protection. The DC
motor has to be connected to this module.
The daughter board and the mother board are provided already properly plugged .
