ST X-NUCLEO-OUT07A1 Bedienungsanleitung

Introduction

The X-NUCLEO-OUT07A1 is an industrial quad digital output expansion board for STM32Nucleo. It provides a powerful and

flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS4260LM quad low-side, smart power,

solid-state relay in a digital output module connected to four 0.7 A industrial loads. The system is also designed to facilitate the

user to configure the application as a dual digital output module for 1.0A industrial loads, or as a single digital output module for

2.0A industrial loads.

The X-NUCLEO-OUT07A1 interfaces with the microcontroller on the STM32Nucleo via STISO620 and STISO621 digital

isolators, and via an isolated dc-dc converter (DC1). The galvanic isolation between the industrial field and Arduino® UNO R3

connectors is guaranteed up to 3kV by the digital isolators and DC1.

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 X-NUCLEO-OUT07A1 expansion board stacked on other expansion board

compatible in terms of logic signals assignments..

1.1 Overview

The X-NUCLEO-OUT07A1 embeds the IPS4260LM intelligent power switch (IPS), which features overcurrent and

overtemperature protections for safe output load control, and open load detection. The overcurrent protection

threshold can be configured by a resistor connected between the RILIM pin and the ground: the onboard

connector J8 allows the easy selection of the most typical current limitation levels (0.5A, 1.0A, 2.0A). Also, the

overcurrent protection can be combined with the low dissipative current limitation feature (cutoff) that limits the

time duration of the overload event by a resistor mounted between RCOD and ground. The same connector J8 can

disable the cutoff feature by closing J8[7-8], if necessary (for example, in case of high capacitive loads). The open

load detection can be enabled closing J7 [1-2, 3-4, 5-6, 7-8] or disabled (J7 open).

The board is designed to meet the application requirements for the galvanic isolation between the user and power

interfaces: the isolation is implemented through one monodirectional digital isolator (STISO620 for cumulative

diagnostic signals FAULT and OL), four bidirectional digital isolators (STISO621 for INX driving signals and

related per-channel overload diagnostic) and an isolated DC-DC converter (DC1, generating the 5V and 10V rails

on the process stage from the 5V rail on the logic side).

The expansion board features:

• Based on the IPS4260LM quad low-side switch, which features:

– Operating range from 8 to 50 V

– High Speed operation (trise, tfall < 1us)

– Process stage operating current: configurable from 350 mA (per channel) up to 2A (parallelized

channels)

– Low-power dissipation (RON(TYP) = 260 mΩ)

– Configurable low dissipative cutoff function in overload conditions

– Per-channel overload, short circuit, and thermal junction protections

– Fast decay for inductive loads (VOUT clamp)

– Open load detection

– Undervoltage lock-out

– Loss of ground protection

– HTSSOP20 package

• Galvanic isolation between logic side and process stage by STISO620, STISO621 digital isolators and

isolated DC-DC converter

• Selectable supply of the IPS4260LM from on board isolated DC-DC converter (SW7 close 1-2), or from 24

V supply rail (SW7 close 2-3)

• Process stage operating range: 10 V (SW7 close 1-2) or 10 V to 30 V (SW7 close 2-3)

• Process stage supply rail reverse polarity protections (J1 open)

• Application board logic side operating voltage 3.3 V or 5 V

• Green LEDs for outputs on/off status (J6 close 1-2, 3-4, 5-6, 7-8)

• Open load detection enable (J7 close 1-2, 3-4, 5-6, 7-8)/disable (J7 open)

• Red LEDs for overload and thermal warning (D8) and open load (D6) diagnostic

• Selectable current limitation level (J8[1-2, 3-4, 5-6])

• Cut-Off enable (J8 open 7-8)/disable (J8 close 7-8) options

• Per channel overload diagnostic available on Arduino (CN5[9,10], CN8[5, 6])

1.1.1 Digital section

The digital section is associated with the STM32 interface and the digital supply voltage to and from the X-

NUCLEO-OUT07A1 expansion board.

Figure 2. X-NUCLEO-OUT07A1 expansion board: digital interface section

The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino®

UNOR3 connectors.

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 X-NUCLEO-

OUT07A1 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 CN4 connector (not mounted by default) on the

expansion board and the ground loop should be closed by mounting D6 (enabling the reverse polarity protection)

or by closing J5 (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.

1.1.2 Power section

The X-NUCLEO-OUT07A1 offers four connections points for the loads through the connectors CN2 and CN3. The

other sides of the load are connected to the positive rail of the process stage power supply (usually +24V).

The X-NUCLEO-OUT07A1 offers the user two alternative solutions to supply the IPS4260LM (U1).

With the default solution (J7 closed 1-2), the IPS4260LM is supplied by the onboard isolated DC-DC converter

DC1 that generates the 10V rail supplying the IC. In this case the user just needs to connect the process side

ground of the X-NUCLEO-OUT07A1 (CN1[2]) to the reference voltage of the process stage power supply where

the loads are connected.

With the alternative supply solution (J7 closed 2-3), the IPS4260LM is supplied by the same supply rail where the

load are connected (CN1[1] connected to the 24V rail).

It is important to note that:

• If default supply of IPS4260LM is selected, then the only allowed external fast demagnetization is by D9

(J8 close 1-2). In other words, setting J8 close 2-3 means to enable IPS4260LM internal fast

demagnetization with the EAS limits reported in the datasheet.

• If IPS4260LM is supplied by the process stage power supply, then D9 (J8 close 1-2) or D10 (J8 close 2-3)

can be used. Also, slow demagnetization can be set (J8 close 2-3 and J3 closed).

For EMC:

• the SMC30J30CA transient voltage suppressor (U2), enabled by closing J2, is placed between process

stage supply rail and GND tracks to protect the IPS4260LM against surge discharge on the supply rail path

up to ±500 k/2 Ω coupling;

• in the common mode surge testing, two single-layer capacitors (C11 and C12 - not included) must be

soldered at the predisposed locations;

• the IPS4260LM 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 X-NUCLEO-OUT07A1 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
