3.1
System Hardware Overview
The Motor Driver Board, with a power rating of 350W, has a high level of usage flexibility
underlines by its modular assembly and is built primarily for the 8 bits Infineon
Microcontroller operation of Brushless DC motor in the E-bike Motor Control System
Development. The secondary usage of LV-MDB board includes the operation of BLDC
sensorless, Resolver, Tachometer, Encoder and PMSM control methodology without the
need of any add-on hardware.
As an Evaluation Board, this drive inverter is not a certified inverter. It does not have a
protection housing and galvanic isolation. In case of improper use, wrongful installation
or misuse, there is a danger of serious physical injury and damage to the property. Direct
contact to the voltage links, hot surfaces and any part of the system must be avoided
when the motor is running. A differential probe must be used when measuring the gate
voltage; Vu, Vv, Vw.
When connecting the Motor Driver Board to the isolating line transformer, copper wires
with a cross-section of at least 0.75mm2 (AWG 20) must be used.
For continuous operation, a heatsink with a better thermal performance is needed, which
depend on the maximum ambient temperature, and mounting proposals for the use of
thermal grease and other interfacing materials.
The BEMF circuitry is not populated on the Motor Driver Board. It is implemented when
the microcontrollers other than the Infineon Technologies microcontorllers without the
ADC peripherals are used. The user is recommended to use LM339D comparator for the
BEMF circuitry.
All operations serving transport, installation and commissioning as well as maintenance
are to be carried out by skilled personnel. For the purpose of safety, “Skilled personnel”
is referred to Engineers who are familiar with the installation, mounting, commissioning
and operation of the Motor Driver Board. A protection housing is required if the Motor
Driver Board is operated in areas where it is accessible by unskilled operators.

Power Stage and Overcurrent Protection
3.3.1
Power Stage
The power stage includes the Infineon Technologies OptiMOS Power-Transistor
modules, SPB80N08S2-07, the gate driver IC and a shunt-resistor for current
measurement and over-current protection.
The minus potential of the Terminal Block , N-, is the Reference ground for the entire
control circuitry. With that the polarity of the shunt signal fits to the pins of the gate driver
IC, no additional signal inverter is needed in the over-current protection path. However,
special attention is needed when ploting the PCB layout with this configuration.
The ground tracks of the Microcontroller section (VSSP), the current signal amplifier
(VAGND) and the power ground (N-) are connected in star configuration at the minus
potiential of the Terminal Block, at the side of the current measurement shunt. They must
be kept strictly separated before converging to the common reference point. The
bootstrap buffer capacitor (C16) must be connected to the common reference trace
(N2X) of the low-side MOSFETs with an individual copper trace.
Note: Do not connect the bootstrap buffer capacitor (C16) to the signal ground.
The high peak current in the bootstrap current loop will cause ground
noises and it is often the main reason for the unstable performance and
operation of the board.
The current amplifier (U3) is connected to the AD input, P2.3 (AN3), of the
Microcontroller via Jumper JP13 to enable easy software current control loop
implementation.
3.3.2
Over-current Protection
A shunt resistor is placed at the minus potential path of the Terminal Block for overcurrent and short-circuit protection purpose. This is the most inexpensive solution which
provides a full proteciton against over-current causes by an overloaded motor or a shortcircuit between the three motor phases; Vu, Vv, Vw.
However, a short-circuit between the three motor outputs (U,V,W), the minus potential
of the Terminal Block and at any of the metallic parts which are connected to the
Reference Ground (RG) cannot be readily detected. It can destroy the Motor Driver
Board immediately.
The voltage across the shunt resistor (R28) is filtered by R19, R29 and C14 and fed to
the over-current comparator of the gate driver IC (ITRIP). This is to turn-off and pulldown all MOSFETs gates when the voltage at this comparator exceeds the internal
reference voltage.

Auxiliary Supply
Figure 3-4
Auxiliary Supply Circuitry
In order to have one power supply source to the boards, an auxiliary supply circuitry is
included into the LV-MDB.
When the power source is plugged in, the auxiliary supply circuitry implemented on the
LV-MDB provides a voltage supply, VS = 15Vdc, to the Starter-kit via the header CN2
Pin 4. A reverse supply of VDDP from the Start-kit is supplied to the LV-MDB via the
header CN2 Pin 2.
Note: If input Voltage P+ > 35V, remove C1, and you may add an additional resistor
at R88 to reduce the power dissipation on U1; if P+ > 45V, remove the
auxiliary supply circuitry. +15V is supplied separately via CN2 Pin 4 either
from the external source or the Starter-Kit independent supply.
Note: During the testing and implementation stage, it is advisable to power the
Starter-kit and LV-MDB separately.

Low Voltage Motor Driver Board (MDB_LV45G_V1.1)
Hardware Installation Guide

Hardware Installation Guide
This system comprises Infineon XC866 Microcontrollers Starter-kit and Motor Driver
Board.
5.1
Hardware Installation Overview
The installation and cooling of the appliances shall be in accordance with the
specification in the relevant documentation.
The Motor Driver Board must be protected against excessive strains. No components
must be bent or isolating distances altered in the course of transportation or handling.
The Motor Driver Board contains electrostatic sensitive components which are liable to
damage through improper use or handling. Electric components must not be
mechanically damaged or destroyed (potiential health risks).
5.1.1
Electrical Connection
The Motor Driver Board is tuned to power up with an input voltage supply of 20V.
Installation which include the XC866 Starter-kit and Motor Driver Board shall be
equipped with additional control and protective devices in accordance with the relevant
application safety requirements, e.g. accident prevention rules etc. Changes to the Motor
Driver Board by means of the Operating Software is admissible.
The electrical installation must be carried out in accordance with the relevant
requirements(e.g. cross-sectional areas of conductors, fusing, PE connection).
Observance of the limit values required by EMC laws is in the responsibility of the user.
After disconnection of Motor Driver Board from the voltage supply, live appliance parts
and power terminals must not be touched immediately because of possibly charged
capacitors.
The capacitor C1 must be removed if the input voltage is greater than 35V. If the input
voltage is greater than 45v, the auxiliary supply circuitry must be removed from the Motor
Driver Board.
Note: The maximum voltage rating of board is limited by the voltage regulator
LM317HVT. The maximum voltage rating of the MOSFETs is 75V.
The resistors values of R55, R56, R57, R58, R59, R60, R75 and R76 must be
recalculated should the input voltage deviate from the normal operating input voltage, P+
= 20V.
Note: The mentioned resistors must be verified and change accordingly before
increasing the input voltage, P+. The reference voltage, ADC and
P+_VAREF, which has a voltage limit of 5V increases with P+. The
incremental reference voltage will damage the microcontroller when it
exceeds the microcontroller’s port voltage tolerant.

5.1.2
Step-by-Step DC Power Installation Guide
• Power up the DC power supply and adjust the voltage supply to 20Vdc. Limit the
current supply to 500mA.
• Connect the DC power supply to Terminal Block P1. The connection polarity is
important here.
• When the power connection is correctly done, the auxiliary power LED D1 will
illuminate.
5.1.3
Step-by-Step Motor Setup Guide
•
•
•
•
Connect the 3-Phase BLDC Motor wires to the Connector P2.
Polarity orientation is important here and is subjective to the motors used.
Connect the Hall sensor wires to JP 1A.
Set the Jumpers of JP3, JP6 and JP11 to Hall-sensor mode. (Place the Jumpers to
Pin 2 and 3 of JP3, JP6 and JP11).
• Hold on to the reset button on the Starter-kit before powering up the boards. Release
the reset button when the board is power up.
• The BLDC motor will spin when the connection is down correctly.
Note: The software need to be modified to accomodate to different motors used.

Current Sensor Comparator Hardware modification
The original hardware connection will result in having a negative signal output from the
comparator U3. Therefore one end of the resistor R27 is to connect to the high side of
the shunt resistor R28 and the low side of the shunt resistor is to be connected to the
other end of resistor R30.
