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 manufacturing 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.

3 Introduction

The KIT33811EGEVBE Evaluation Board is a simple circuit for exercising the 33811 IC.

The 33811 is a 5 channel Solenoid Monitor IC that is used to verify proper electrical and
mechanical solenoid operation. The IC contains five solenoid driver voltage monitoring
stages and a serial peripheral interface (SPI) for fault communication and setup. The IC
has the ability to determine the correct movement of solenoid armatures by analyzing
the variation in the voltage profile, across the solenoid driver MOSFET, which
represents the actual solenoid current profile.
