Data brief
Description
STEVAL-VNH5019A offers dedicated power
stage and controls suitable for electric DC motor
driving. This evaluation board comes
pre-assembled with VNH5019A H-bridge
belonging to the VNH Motor Driver series based
on VIPower^® proprietary technology. Typical
applications are Windows Lift, Sliding Door, 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 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 VNH5019A
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.
