DC Motor Control HAT with
TLE94112ES
Quick Start Guide
V1.0.0
- restricted -

Introduction
The TLE94112ES HAT is a DC Motor Control board that is capable to drive up to six
independent or eleven cascaded bidirectional DC motors.
The HAT can be controlled by a Raspberry Pi board via an SPI interface and features an
Infineon TLE94112ES, a twelve-fold half-bridge driver with integrated MOSFETs.
The HAT has an active reverse polarity protection with the p-channel MOSFET IPD50P04P4L-
11 and is able to power a Raspberry Pi via the DC/DC-converter TLS4125D0EP 50V. To ensure
the use of multiple HATs on one Raspberry Pi the CS pin can be changed via jumpers.
All software is released into the public domain and available as open source libraries on GitHub.

HAT Notes
›Supply voltage is typ. 12V (max. 20V)
›All outputs can drive up to 0.9A
›Outputs can be used stand-alone or combined to increase driving capability up to
3.6A
›The default CS-pin is CS0, but it can be changed via jumpers to CS1, CS2 or
CS3
›Via pin header 8 the input voltage can be bridged to another HAT

EEPROM
›The HAT includes an EEPROM which stores vendor, product and interface
information and can automatically enable the SPI interface of the Raspberry Pi.
›In case multiple HATs are stacked, the EEPROM on all but one HAT need to be
disabled. This can be done by closing the solder bridge marked with A+1

Getting Started
›Connect
–the HAT to the Raspberry Pi via the 40 pin pinheader,
–a 12V power supply unit to VBAT and GND (The Pi is also powered now)
and
–aDC motor to outputs 1 and 5

Getting Started (Software)
›As soon as the Pi is powered, make sure it is connected to the internet
–Either via Wi-Fi or via an ethernet cable
›There are two options to access the Raspberry Pi
–Connect the Pi via a HDMI cable to a monitor
–or download Putty and access the Pi via its IP address

Getting Started (Software)
›When the Pi is all set up, go to Infineon GitHub
›Look for multi-half-bridge, you can find all information there
›Clone the git repository with
git clone https://github.com/Infineon/multi-half-bridge.git
–This repository includes the TLE94112ES library and usage examples

Getting Started (Software)
›The bcm2835 library provided by airspayce is required by the library and can be
installed automatically, using the script install_requirements.sh in
src/framework/raspberrypi
›For this, execute
–cd multi-half-bridge/src/framework/raspberrypi
–sudo chmod +x ./install_requirements.sh
–./install_requirements.sh
–More information about this library can be found here

Getting Started (Software)
›For a quick first test, example code can be found here:
/src/framework/raspberrypi/examples
›To compile the basicTest example
–execute „cd /src/framework/raspberrypi/“
–and then compile the code with „make examples/basicTest“.
–if you compiled another example before execute „make clean“ before compiling
›To run the code on the Raspberry Pi
–change to folder „build“ and execute the code
–../../../build/basicTest
