STMicroelectronics STEVAL-IFP040V1 Industrial Digital Output Expansion

Board

Introduction

The STEVAL-IFP040V1 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 IPS1025HFQ single high-side, smart power, solid-state relay in a digital output module connected to 2.5 A industrial loads.
The STEVAL-IFP040V1 can interface with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by the GPIO pins and Arduino® UNO R3 connectors.
The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO- G431RB development board.
You can also evaluate a system consisting of an STEVAL-IFP045V1 stacked on an STEVAL-IFP040V1 expansion board.
Supplying the STEVAL-IFP045V1 through the main supply rail and the STEVAL- IFP040V1 through the output of the STEVAL-IFP045V1, you can achieve the typical architecture of a single channel digital output for safety systems. The process stages of the two expansion boards result cascaded. The load connected to the STEVAL-IFP040V1 output can be supplied only when both cascaded systems are properly working.

Overview

The STEVAL-IFP040V1 embeds the IPS1025HFQ intelligent power switch (IPS), which features overcurrent and overtemperature protection for safe output load control. The IC also offers the quick activation of its output stage even at power-up. In fact, the input to the output propagation delay at startup is guaranteed ≤ 60 µs.
The board is designed to meet the application requirements for the galvanic isolation between the user and power interfaces.
An optical isolation satisfies this requirement. The isolation is implemented through five optocouplers (ISO1, ISO2, ISO3, ISO4, and ISO5) for the input signal forward to the device, the FLT diagnostic feedback signals of the device, and two additional signals for safety application optimization (Nch- DRV for the fast discharge control of the output voltage, and OUT_FB for the on/off status monitoring of the output stage).

The expansion board features:

Based on the IPS1025HFQ single high-side switch, which features:
- Operating range up to 60 V
- Low-power dissipation (RON(MAX) = 25 mΩ)
- Propagation delay at startup < 60 µs
- Fast decay for inductive loads
- Smart driving of capacitive load
- Under-voltage lock-out
- Overload and overtemperature protections
- QFN48L 8×6 mm package
Application board operating range: 8-33 V/0-2.5 A
Extended voltage operating range (J3 open) up to 60 V
Green LED for output on/off status (J11 close 3-4 and SW5 close 1-2)
Red LEDs for overload and overheating diagnostics (SW2 and SW4 close 2-3)
Output voltage on/off status feedback (J11 close 1-2)
Control signal for fast discharge of output voltage (J11 close 5-6, J12 close)
External fast discharge circuitry for huge inductive loads (J11 close 7-8)
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

Digital section

The digital section is associated with the STM32 interface and the digital supply voltage to and from the STEVAL-IFP040V1 expansion board.
Figure 2. STEVAL-IFP040V1 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino® UNO R3 connectors. STMicroelectronics-
STEVAL-IFP040V1-Industrial-Digital-Output-Expansion-Board-
FIG-1

The four Arduino® UNO R3 connectors:

allow the expansion board to communicate with the STM32 Nucleo development board microcontroller accessing the STM32 peripheral and GPIO resources;
provide the digital supply voltage between the STM32 Nucleo development board and the STEVAL-IFP040V1 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 the 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 the JP5 jumper between pins 2 and 3 and open the JP1 jumper on the NUCLEO-F401RE;
open the JP5 jumper between pins 1 and 2 and close the JP5 jumper between pins 3 and 4 on the NUCLEO-G431RB.

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 Section 2 Schematic diagrams) and electromagnetic compatibility (EMC) protection.

Board-FIG-2

For EMC:

the SM15T39CA transient voltage suppressor (TR1), enabled by closing J3, is placed between VCC and GND tracks to protect the IPS1025HFQ against surge discharge on the supply rail path up to ±1 kV/2 Ω coupling;
in the common mode surge testing, two single-layer capacitors (C1 and C2 – not included) must be soldered at the predisposed locations;
the IPS1025HFQ 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.

The EMC performances of the STEVAL-IFP040V1 are detailed below:

for emission, compliance with standards:
- EN IEC 61000-6-3:2021
- EN 55032:2015 +A1:2020
for immunity, compliance with standards:
- EN IEC 61000-6-1:2019
- EN 55035:2017 +A11:2020

Hardware requirements

The STEVAL-IFP040V1 expansion board is designed to be used with the NUCLEO- F401RE or NUCLEO-G431RB STM32 Nucleo development boards.
To function correctly, the STEVAL-IFP040V1 must be plugged onto the matching Arduino® UNO R3 connector pins on the STM32 Nucleo development board as shown below.
