EVAL-VNH5019-P2
Dual VNH5019 Motor Driver Shield Arduino-Compatible
Features
• Wide operating voltage range: 5.5 - 24 V
• High output current: up to 12 A continuous (30
maximum) per motor
• Motor outputs can be combined to deliver up to
24 A continuous (60 A maximum) to a single
motor
• Inputs compatible with both 5 V and 3.3 V
systems (logic high threshold is 2.1 V)
• PWM operation up to 20 kHz for quieter motor
operation
• Current sense voltage output proportional to
motor current
• Motor indicator LEDs show what the outputs
are doing even when no motor is connected
• Can be used with Arduino compatible boards,
SPC56P-Discovery, STM32 Nucleo or other
microcontroller boards
• When used as a shield, the motor power supply
can optionally be used to power the Arduino
base as well
• Arduino pin mappings can be customized if the
default mappings are not convenient
• Arduino library or SPC5Studio makes it easy to
get started using this board as a motor driver
shield
• Reverse-voltage protection
• Robust drivers:
Data brief
– Can survive input voltages up to 41 V
– Undervoltage and overvoltage shutdown
– High-side and low-side thermal shutdown
– Short-to-ground and short-to-Vcc
protection
Description
This motor driver shield makes it easy to control
two bidirectional, high-power, brushed DC motors
with an Arduino-Compatible, SPC56P-Discovery
and STM32 Nucleo boards. The board features a
pair of robust VNH5019A motor drivers, which
operate from 5.5 to 24 V and can deliver a
continuous 12 A (30 A peak) per channel, and
incorporate most of the components of the typical
application, like pull-up's and protection resistors
and FETs for reverse battery protection.
This versatile motor driver is intended for a wide
range of users, from beginners who just want a
plug-and-play motor control solution for their
Arduinos and Nucleo to experts who want to
directly interface with ST's great motor driver ICs.
The Arduino pin mappings can all be customized
if the defaults are not convenient and the
VNH5019A control lines are broken out along the
left side of the board for general-purpose use
without an Arduino. This versatility, along with an
option to power the Arduino directly from the
shield, set this board apart from similar competing
motor shields and it is as well a perfect tool to
evaluate VNH5019A performance.
