The ICON H-Bridge is the first component of the ICON DC Motor Control
system designed to be a low cost, and modular, solution to brushed DC motor
control needs. This 2.5"x1.9" board provides logic level control of brushed
DC motors to 40V and 12A. An on board microcontroller can be accessed via
standard serial communication, and provides temperature and current monitoring,
as well as user defined temperature and current fuse settings.
The ICON H-Bridge provides easy connectivity to a wide range of medium
power DC motors. An on-board microcontroller monitors current and temperature
to provide protection if either trip point is exceeded. Various configuration
registers may be monitored and programmed via the serial interface. These
registers contain information such as the system load current, board temperature,
over current trip point, over temperature trip point, and status information.
In Serial mode the H-bridge is enabled/disabled via a serial command
set. In Direct Drive mode the serial input line becomes the H-bridge enable
control pin, while the serial output can be used to monitor the H-bridge
status. In both operating modes each MOSFET in the H-bridge is controlled
individually by a control input (four MOSFET control lines in all).
The ICON H-Bridge is designed to operate with motor voltages up to 40V
and can carry continuous currents up to 12A when combined with the
Active Cooling System. This robust
H-Bridge handles peak currents of 25A and has built in, programmable, over-current
and over-temperature trip points.
Connectivity to the ICON H-Bridge is simplified to 2 - 1x8 0.156" receptacles
capable of top or bottom insertion of 1x8 0.156" headers. With the small
size (2.5"x1.9"x0.5") and versatile interface capabilities of the ICON H-Bridge,
it meets the requirements of many DC motor interface designs.

ICON Serial Adapter
Simplifies connectivity of the ICON Interface Module to a PC. Provides
test points, analogue output, and connectivity to Microchip's DV164002
for customization of PIC16F873 firmware used on the ICON Interface
Module (see AN601).
ICON Position Controller
PID based position controller for use with brushed DC motors equipped
with quadrature encoders. Direct, Analogue, Velocity, or Trapezoidal
control modes with 32 bit position control. Can act as a stand alone
position controller or will work under control of a master unit.
Operates with the ICON H-Bridge configured in direct drive mode.
ICON Interface Module
Can act as the ICON H-Bridge Programmer. Other features of this
design include uni-directional and bi-directional analogue control,
serial 8N1, or motor speed control for use with the ICON H-Bridge.
Set point based speed control system, or direct PWM control via
communication interface.
ICON Communication Module
The ICON Communication Module is designed to simplify testing and
development of projects requiring RS232 or RS485 serial communication
level conversion. The device can be mounted directly to the ICON
Interface Module, ICON Position Controller, or the Mini Position
Controller using supplied stand-offs and ribbon cable hardware.
ICON BS2 Carrier Board
This kit based on application note AN600 allows a single Parallax
BASIC Stamp 2 to control two ICON Interface Modules and the ICON
H-Bridges connected to them. This assembly is ideally suited for
medium sized robotics projects. Various application notes are available
to support this product.
12V Active Cooling System
This fan, hardware, and connector kit can be easily added to the
ICON H-Bridge to increase continuous current handling capability
to 12A.
