STEVAL-VNH5050A:VNH5050A Evaluation Board

STEVAL-VNH5050A offers dedicated power stage and controls suitable for electric DC motor driving. This evaluation board comes pre-assembled with VNH5050A 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 daughterboard.

The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the VNH5050A assembled in the daughterboard.

With the aim to make simpler the board usage and settings, ST provides a dedicated and user-friendly software with a Graphic User Interface (GUI). This enables the user to set VNH5050A parameters (PWM, Motor direction…) and at the same time it shows real time device diagnostic information like current output evolution, battery voltage monitoring, board temperature and much more.

Key Features
