Introduction
Handling high power in a drives application demands an optimized thermal management combined with
high-performance MOSFETs.
Modern silicon packaged into the new TO-Leadless allows the designer to reach a higher motor power
without the need of excessive parallelization.
Infineon offers with these demoboards a solution for applications like Light Electric Vehicles (µCars, forklifts,
E-Scooters) a power platform for first evaluations.
Depending on the overall heat sinking system the Power Boards easily can handle 5kW and more, allowing
investigations regarding switching and temperature behavior.
The TO-Leadless (P/PG-HSOF-8-1) is a molded package optimized for high power and high reliability
applications. It´s small mechanical dimensions allows compact designs and the high current capability
combined with the low thermal resistance (Rth(j-c)), resulting in lower chip temperatures, enable the designer
to go for higher power density and higher reliability.
All mechanical details shown in the following chapters and additionally a general recommendation how to
handle Infineon´s SMD devices could be found at www.infineon.com/packages.
Detailed mechanical information about the TO-Leadless (P/PG-HSOF-8-1) is available at TO-Leadless.
General information like datasheets, product brief etc. are available under www.infineon.com/toll.

Board description
2.1
Setup
The board offers all necessary power parts to handle several kilowatts. Depending on thermal management
and electrical environment much more than 5kW of motor power are possible.
The board contains 3 halfbridges with 5 MOSFETs in parallel per switch. All power paths offer the possibility
to connect wires via bolts or screws. Three connectors, each for PLUS and MINUS have to be wired together
externally (dotted lines in Figure 2.3). A well suited electrolytic capacitor bank (Low ESR) has to be
connected as close as possible to the connectors for PLUS and MINUS.
Depending on the current measurement system additional shunt resistors could be added between the
halfbridge´s MINUS contacts and the common MINUS.
Gate resistors are included to optimize the switching speed. If necessary an additional external resistor could
be added in the gate drive circuit. Additional source resistors (1Ohm) between the power board and the
external driver circuit could avoid high currents between the sources of the halfbridges via the driver board.
R11 is not assembled but offers the possibility to add a NTC or a PTC.
