2 Important Notice

Freescale provides the enclosed product(s) under the following conditions:
This evaluation kit is intended for use of ENGINEERING DEVELOPMENT OR EVALUATION PURPOSES ONLY. It is

provided as a sample IC pre-soldered to a printed circuit board to make it easier to access inputs, outputs, and supply
terminals. This EVB may be used with any development system or other source of I/O signals by simply connecting it
to the host MCU or computer board via off-the-shelf cables. This EVB is not a Reference Design and is not intended to
represent a final design recommendation for any particular application. Final device in an application will be heavily
dependent on proper printed circuit board layout and heat sinking design as well as attention to supply filtering, transient
suppression, and I/O signal quality.

The goods provided may not be complete in terms of required design, marketing, and or manufacturi ng related
protective considerations, including product safety measures typically found in the end product incorporating the goods.
Due to the open construction of the product, it is the user's responsibility to take any and all appropriate precautions with
regard to electrostatic discharge. In order to minimize risks associated with the customers applications, adequate design
and operating safeguards must be provided by the customer to minimize inherent or procedural hazards. For any safety
concerns, contact Freescale sales and technical support services.

Should this evaluation kit not meet the specifications indicated in the kit, it may be returned within 30 days from the date
of delivery and will be replaced by a new kit.

Freescale reserves the right to make changes without further notice to any products herein. Freescale makes no
warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does
Freescale assume any liability arising out of the application or use of any product or circuit, and specifically disclaims
any and all liability, including without limitation consequential or incidental damages. “Typical” parameters can and do
vary in different applications and actual performance may vary over time. All operating parameters, including “Typical”,
must be validated for each customer application by customer’s technical experts.

Kit Introduction

3 Kit Introduction

• The KIT33932VWEVBE Evaluation Board (EVB) is an easy-to-use circuit board that
allows the user to exercise all the functions of the MC33932 H-Bridge circuit. The EVB
parallel input can be easily controlled through a USB/SPI Dongle connected to a PC’s
USB port. The Freescale SPIGen program provides the User Interface to the USB/SPI
Dongle and allows the user to send commands to the IC.

The Hardware Block Diagram is shown below:

Hardware Description

This EVB consists of a Dual H-Bridge, a parallel interface, power conditioning circuitry, and a set of 8 Input Select Jumpers.

All +5 volt VDD power required by the EVB is obtained via the parallel interface.

4.2 LED Display

Several LED’s are provided as visual output devices for the EVB. A list of the LED devices is shown below:

1. VDD LED - Indicates when +5 Volt supply is connected

2. VPWR LED - Indicates when +12 Volt supply is connected

3. Fault LEDs - Illuminates when one of the H-Bridges detects a fault

4. Output LEDs - Red/Green LED, for each H-Bridge, that indicates which direction the current is flowing in the legs of the
H-Bridge.
