ST STEVAL-IFP046V1 User manual

Introduction
The STEVAL-IFP046V1 is an industrial digital output expansion board. It provides a powerful and flexible environment for the
evaluation of the driving and diagnostic capabilities of the IPS1025HQ-32 single high-side smart power solid state relay, in a
digital output module connected to 5.7 A industrial loads.
The STEVAL-IFP046V1 can interface with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by GPIO pins
and Arduino R3 connectors.
The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.
It is also possible to evaluate a system composed of up to four stacked STEVAL-IFP046V1 expansion boards.
As an example, a system with four STEVAL-IFP046V1 expansion boards allows you to evaluate a quad channel digital output
module.

1.1 Overview
The STEVAL-IFP046V1 embeds the IPS1025HQ-32 intelligent power switch (IPS), featuring overcurrent and
overtemperature protection for safe output load control.
The board is designed to meet application requirements in terms of galvanic isolation between user and power
interfaces. This requirement is satisfied by an optical isolation implemented through three optocouplers (ISO1,
ISO2, and ISO3) for signal forward to the device and FLT pins for feedback diagnostic signals.
The expansion board features:
• Based on the IPS1025HQ-32 single high-side switch, which features:
– Operating range up to 60 V
– Low-power dissipation (RON(MAX) = 25 mΩ)
– Fast decay for inductive loads
– Smart driving of capacitive loads
– Undervoltage lock-out
– Overload and overtemperature protections
– QFN48L 8x6 mm package
• Application board operating range: 8 to 33 V/0 to 5.7 A
• Extended voltage operating range (J3 open) up to 60 V
• Green LED for output on/off status
• Red LEDs for overload and overheating diagnostics
• 5 kV galvanic isolation
• Supply rail reverse polarity protection
• Compatible with STM32 Nucleo development boards
• Equipped with Arduino UNO R3 connectors
• CE certified
• RoHS and China RoHS compliant
• Not FCC approved for resale
1.1.1 Digital section
The digital section is associated with the STM32 interface and digital supply voltage to and from the STEVAL-
IFP046V1 expansion board.

UM3058 - Rev 1 page 2/19

Figure 2. STEVAL-IFP046V1 expansion board: digital interface section
Dotted green line indicates the whole digital interface section. Pink rectangles identify Arduino UNO R3 connectors
The four Arduino UNO R3 connectors:
•allow expansion board communication with the STM32 Nucleo development board microcontroller accessing
STM32 peripheral and GPIO resources;
• provide digital supply voltage between the STM32 Nucleo development board and the STEVAL-IFP046V1
expansion board, in either direction.
Normally, the STM32 Nucleo development board supplies the expansion board by a 3v3 or 5v0 generated by the
USB. You can select the preferred voltage on the expansion board via SW3 (3v3 closing pins 1-2; 5v0 closing
pins 2-3).
Alternatively, it is possible to supply the STM32 Nucleo development board by the expansion board. In this case,
an external supply voltage (7-12 V) should be connected to CN2 connector (not mounted by default) on the
expansion board and the ground loop should be closed by mounting D2 (enabling the reverse polarity protection)
or by closing J2 (without reverse polarity).
To supply the VIN voltage rail, it is necessary to:
• close jumper JP5 between pins 2 and 3 and open jumper JP1 on the NUCLEO-F401RE;
• open jumper JP5 between pins 1 and 2 and close jumper JP5 between pins 3 and 4 on the NUCLEO-
G431RB.

1.1.2 Power section
The power section involves the power supply voltage (CN1, pins 4 and 5 for VCC, pin 3 for GND), load
connection (a load can be connected between pins CN1.1 and CN1.3 or CN1.2, and CN1.3; both output pins
are connected to the single output channel as shown in Schematic diagrams) and electromagnetic compatibility
(EMC) protection.

For EMC:
•The SM15T39CA transient voltage suppressor (TR1), enabled by closing J3, is placed between VCC and
GND tracks to protect the IPS1025HQ-32 against surge discharge on the supply rail path up to ±1 kV/2 Ω
coupling;
• in common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soldered at
the predisposed locations;
• the IPS1025HQ-32 output stages do not require additional EMC protections with respect to the
IEC61000-4-2, IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-8 standards.

1.2 Hardware requirements
The STEVAL-IFP046V1 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-
G431RB STM32 Nucleo development boards.
To function correctly, the STEVAL-IFP046V1 must be plugged onto the matching Arduino UNO R3 connector pins
on the STM32 Nucleo board as shown below.
Figure 4. STEVAL-IFP046V1 and STM32 Nucleo stack
1.3 System requirements
To use the STM32 Nucleo development boards with the STEVAL-IFP046V1 expansion board, you need:
• a Windows PC/laptop (Windows 7 or above)
• a type A to mini-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-
F401RE development board
• a type A to micro-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-
G431RB development board
• the X-CUBE-IPS firmware and software package installed on your PC/laptop
1.4 Board setup
Step 1. Connect the micro-USB or mini/USB cable to your PC to use the STEVAL-IFP046V1 with NUCLEO-
F401RE or NUCLEO-G431RB development board

Step 2. Download the firmware (.bin) onto the STM32 Nucleo development board microcontroller through
STM32 ST-LINK utility, STM32CubeProgrammer and according to your IDE environment as detailed in
the table below.

Step 3. Connect the IPS1025HQ-32 device supply voltage via CN1 (see Section 1.1.2 Power section).
Step 4. Provide the digital supply voltage (see Section 1.1.1 Digital section).
Step 5. Connect the load on the output connector (see Section 1.1.2 Power section).
Step 6. Reset the example sequence using the black push button.
Step 7. Push the STM32 Nucleo blue button to select the example provided in the firmware package.
1.5 Multiple board configuration
It is also possible to evaluate a four channel digital output module by stacking four STEVAL-IFP046V1 with shared
or independent supply rail and independent loads.
In this case, the four expansion boards (board 0, 1, 2, 3 as shown in the table below) must be properly configured:
for board 1, 2 and 3, it is necessary to unsolder three resistors for each board from the default position and solder
them back in the alternate positions according to the following table.
