Abstract
Note: The following information is given as a hint for the implementation of the device only and shall not be
regarded as a description or warranty of a certain functionality, condition or quality of the device.
This Application Note is intended to provide information about the TLE7182EM Evalution Board Revision 1.1. The
board is designed to facilitate the evaluation of the Infineon H-bridge driver TLE7182EM.
This document includes a board description, a quick start guide, the schematics and the layout of the board. It is
assumed that the reader is familiar with the driver IC data sheet.
The board itself can be ordered using the usual Infineon Technologies sales channels.
Please make sure that the revision of your evaluation board and the board revision described in this
document (1.1) match before you get started.

Board description
Besides the H-bridge driver itself, the TLE7182EM Evalution Board contains 5 N-Channel Power MOSFETs, a
current sense shunt resistor and other additional components like a 5V regulator to allow operation without a lot
of external equipment. It is designed for automotive 12V applications. This chapter describes all parts of the board.
Schematics and layout are covered in detail in Chapter 4
2.1
Overview
Figure 1 contains the top view of the board.

2.2
Power Supply
The power supply of the board and the load (=motor) has to be connected to the connector X2. Please see
Figure 1 for the required polarity.
2.3
Power Stages and Phase Outputs
Each of the two power stages contain two IPD90N04S04-02 n-channel MOSFETs. One of them is used as a low
side switch, the other one as a high side switch. Two DC link capacitors (220µF and 2.2µF) have been added. It
is possible to add snubber circuits for high side as well as the low side MOSFETs but they are not mounted by
default. The phase outputs are available on the connector X3.
Figure 2 shows the power stage components in detail.

Status LEDs
The TLE7182EM Evalution Board has two status LEDs. The green 5V LED indicates that the 5V voltage regulator
is working correctly. The red ERR LED will light up if there is a warning or an error indication of the bridge driver.
2.5
Solder Bridges
The PCB of the TLE7182EM Evalution Board is also used for the TLE7181EM Evalution Board. The solder bridges
have to be set according to Figure 3.

Drive Card Connector to Microcontroller
The drive card connector is the interface to the microcontroller. It contains the 5V supply voltage for the
microcontroller as well as all relevant connections to input and output pins of the bridge driver. Please see the
schematics in Chapter 4 for a detailed pin description. All jumpers except JP1 (SCDL open) have to be open if a
microcontroller is used.
2.7
Jumpers, Buttons and Potentiometers
The TLE7182EM Evalution Board has several jumpers to simplify usage without a microcontroller, to allow
tweaking of the short circuit detection level (SCDL) and for testing purposes.
2.7.1
ENA jumper JP5 and Reset Button
The ENA pin of the driver IC enables it. ENA can be set to 5V by setting the jumper JP5. ENA can be temporarily
set to GND by pressing the reset button. This will reset the IC. If the device is used with a microcontroller, JP5 has
to be open in order not to override the ENA signal coming from the microcontroller.
2.7.2
R25, R31 and JP4
R25, R31 and JP4 are not used.
2.7.3
Short Circuit Detection Level Configuration
The short circuit detection level can be adjusted with the SCD potentiometer next to the jumper JP1. It has to be
assured that SCDL is within the range specified in the data sheet.
The jumper JP1 has to be set in normal operation mode. In order to test the SCD open pin detection, JP1 can be
removed. In this case the ERR LED has to light up.
2.7.4
JP2
Setting JP2 sets the signal input IL1 to high. JP2 has to be open for normal operation with TLE7182EM.
2.7.5
JP3
JP3 sets the signal input IL2 to low. It has to be open for normal operation with TLE7182EM.

Before You Begin
Please make sure that the revision of your evaluation board and the board revision described in this
document (1.1) match before you get started. The revision number is printed on the PCB as shown in Figure 4.

3.2
Preparation
The same PCB is used for both, the TLE7181EM Evalution Board and the TLE7182EM Evalution Board. Please
check whether the correct H-bridge driver IC is mounted on the PCB.
Please set the solder bridges according to Chapter 2.5.
3.3
Simple Example without a Microcontroller
To drive an external DC-brush motor at the phase outputs, only a few steps are required.
•

•
•
•
•
•
•
•
•
set jumper JP1 (see Chapter 2.7.3) to avoid the SCDL open pin error
set jumper JP5 (see Chapter 2.7.1) to set the ENA pin to high
open JP2 and JP3 which are not used for TLE7182EM
connect a 12V power supply according to Chapter 2.2
connect a DC-brush motor to the outputs OUT1 and OUT2
if the red ERR LED indicates a problem, make sure that the SCDL voltage is within the range specified in the
data sheet. At the time of writing this document, the current data sheet defines a valid range from 0.2..2.0V. If
the SCDL voltage is not within this range, please change it as described in Chapter 2.7.3
if the red ERR LED still indicates a problem, please go through the error conditions specified in the data sheet.
If one or more of them are met, please resolve them
make sure that the bootstrap capacitors are charged by switching on the low side MOSFETs. The PINs of the
drive card connector corresponding to IL1 and IL2 (see Figure 5) have to be set to high to do so
apply valid PWM patterns to the PINs of the driver card connector corresponding to the input signals IL1, IH1,
IL2 and IH2
now the MOSFETs should be switching as defined by the input signals
