Smart High-Side Power Switch - Demoboard
Description
PROFET™ +
1
Overview
The Profet+ demoboard consists of a mother board and a daughter board
which is plugged onto it. In the picture on the right side, both PCBs are
shown.
This demoboard is designed to handle all devices within the PROFET
TM
+
family. Banana connectors are provided for the connection to the power
lines. The motherboard contains the entire application circuitry around
the PROFET
TM
+ device. Additionally, some useful functions, such as the
possibility to connect more than one demoboard to a test set up are
implemented.
Application
•
•
Compatible with the entire PROFET
TM
+ family (1- and 2-channel)
Suitable for evaluation of resistive, inductive and capacitive loads
Features
•
•
•
•
•
•
•
One channel / two channel devices can be evaluated
One board for the complete family
Modularity for fast and easy changing of loads and devices within the PROFET
TM
+ family
Easy indication which switch is optimized for a given load
Only one power supply needed for start up
All logic pins are switchable directly on the board
Also compatible with external logic voltage supplies

Block Diagram
This block diagram gives an overview of the locations of the Jumpers and Dip switches as well as the functionality
behind. For the first start-up please short the Jumper JP1 and connect a voltage source to VS_1/VS_2 and the
GND. The voltage can be chosen within the full range of the PROFET
TM
+ specification.

The PROFET
TM
+ can controlled with either the internal or external signals on the the banana connectors. For (IN0,
IN1, DEN, DSEL) external signal control the respective connector has to be turned off with the respective switch
on the demoboard. If the switch is turned on and there is an external signal, this signal is shorted with the internal
5V or the external High logic 5V.

Function
Connection for the supply of the µC-board and the internal 5V supply
Connection of the power line Vs for the PROFET
TM
+ DUT. It is usually connected with VS_1
on the backside of the board via SJ11 and SJ12
Out0 from the PROFET
TM
+, for one channel devices the single output
Out1 from the two channel PROFET
TM
+, for one channel devices this out is not used
Connection for the module GND, the device GND can be chosen with JP3 or JP5
With these connectors it’s possible to control the logical high / low voltage level with an external
supply

Demoboard Description
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.
Figure 2
Motherboard of PROFET+ demoboard
The picture shows the motherboard of the PROFET+ demoboard. Starting from the banana connectors at the top
of the figure going in a clockwise direction:
•
•
•
•
•
•
VS_1...Connection of Vbat to the Demoboard and also for the internal 5V generation. There are two soldering
jumpers at the bottom side of the motherboard to connect VS_1 with VS_2 (SJ11, SJ12).
VS_2...Connection of Vbat to the PROFET+ VS pin.
Out0...Output 0 of the PROFET+ (for one channel devices the only output)
Out1...Output 1 of the two channel PROFET+, if a one channel device is used this output is not active.
GND...The GND of the demoboard, device ground connection can be chosen with JP3 or JP5.
Logic High 5V...At this pin the logical high voltage which is forced to the logical pins of the PROFET+ could be
controlled from an external supply. Only applicable with the switches at the right side on the motherboard. The
JP2 has to short point 2 and 3 to activate the external voltage. If JP2 shorts 1 and 2 the internal 5V is used
(see
Figure 4).
Logic Low 0V...At this pin the logical low voltage which is forced to the logical pins of the PROFET+ could be
controlled from an external supply. Is only valid with the usage of the switches on the demoboard.
DSEL... Banana connector for external connection to choose the sense signal of Channel 0 or Channel 1, also
can be controlled internally on the board with the switch on the board.
