ST X-NUCLEO-OUT08A1 User manual

Introduction
The X-NUCLEO-OUT08A1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible
evaluation and development environment for 2 A (typ.) digital output modules, featuring the safe driving and smart diagnostic
capabilities of the IPS160HF single high-side switch.
The X-NUCLEO-OUT08A1 interfaces with the microcontroller on the STM32 Nucleo via 3 kV optocouplers driven by GPIO pins
and Arduino™ UNO R3 (default configuration) and ST morpho (optional, not mounted) connectors.
The expansion board should be connected to either a NUCLEO-F401RE or NUCLEO-G431RB development board, and can
also be stacked with another X-NUCLEO-OUT08A1 or X-NUCLEO-OUT10A1.
Two X-NUCLEO-OUT08A1 expansion boards allows you to evaluate a dual channel digital output module with 2 A (typ.)
capability each, or a 2 A (typ.) single channel safety digital output module. In the second scenario, the first shield output is
connected to the supply of the second one. Dedicated on-board hardware can be enabled or disabled to activate fast discharge
of high capacitive loads, output voltage sensing and additional surge pulse output line protection.

1Getting started
1.1 Overview
The X-NUCLEO-OUT08A1 industrial digital output expansion board, embedding the IPS160HF intelligent power
switch (IPS), is designed to meet the application requirement in terms of galvanic isolation between user interface
(or logic side) and power interface (or process side).
This requirement is satisfied by an optical isolation implemented through two couples of optocouplers:
1. The first couple includes:
a. ISO1: for signal forwarding to the device
and
b. ISO2: for diagnostic signal (DIAG pin) feedback
2. The second couple incudes:
a. ISO3: for the additional output voltage feedback signal
and
b. ISO4: for the additional circuitry driving Q1 to allow fast discharge of the output rail
The main features of the X-NUCLEO-OUT08A1 expansion board are:
• Based on IPS160HF single high-side switch, which features:
– Operation up to 60 V/2.4 A
– Low power dissipation (RON(MAX) = 120 mΩ)
– Fast decay for inductive loads
– Open load detection and diagnostics
– Overload and overheating protections with thermal shut-down and cut-off
– PowerSSO-12L package
• Application board operating range: 12 to 33 V/0 to 2.4 A
• Extended voltage operating range (J1 open) up to 60 V
• Status and diagnostic LEDs
• 3 kV galvanic isolation
• Supply rail reverse polarity protection
• Ready for Safety Digital Output Architecture
• EMC compliance with IEC61000-4-2, IEC61000-4-3, IEC61000-4-5
• Wide application development potential in STM32 Nucleo development environment
• Equipped with Arduino™ UNO R3 connectors
• CE certified
• RoHS and China RoHS compliant
1.1.1 Digital section
The digital section is associated with the STM32 interface and digital supply voltage to and from the X-NUCLEO-
OUT08A1 expansion board.
The digital and power sections are isolated by 3.3 mm creepage. Communication between the two sections is
guaranteed by ISO1, ISO2, ISO3 and ISO4 optocouplers.

UM2715 - Rev 1 page 2/15

Figure 2. X-NUCLEO-OUT08A1 expansion board: digital interface components
The four Arduino® UNO R3 connectors:
• allow expansion board communication with the STM32 Nucleo development board accessing STM32
peripheral and GPIO resources;
• provide digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-
OUT08A1 expansion board, in either direction.
Normally, the STM32 Nucleo development board supplies the expansion board by 3v3 or 5v0 (JP5 pins 1-2
closed) generated by the USB. You can select the preferred voltage on the expansion board via SW2 (3v3 by
closing pins 1-2; 5v0 by 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 (that enables reverse polarity protection)
or by closing J3 (without reverse polarity).
To supply the VIN voltage rail 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, pin 1 VCC, pin 2 GND), load connection (between
CN1 pin 3 and CN1 pin 2) and electromagnetic compatibility (EMC) protection (U2).
UM2715
Overview
UM2715 - Rev 1 page 3/15

Figure 3. X-NUCLEO-OUT08A1 expansion board: power stage components
For EMC:
• the transient voltage suppressor (U2), enabled by closing J1, is placed between VCC and GND tracks to
protect the IPS160HF against surge discharge on the supply rail path up to ±1 kV/2Ω coupling;
• in common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soledered at
the predisposed locations;
• the IPS160HF output stages do not require additional EMC protections with respect to IEC61000-4-2 (± 10
kV contact, ±16 kV air), IEC61000-4-4 (± 4 kV), IEC61000-4-5 (± 3.5 kV) standards.
1.2 Hardware requirements
The X-NUCLEO-OUT08A1 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-
G431RB STM32 Nucleo development boards.
To function correctly, the X-NUCLEO-OUT08A1 must be plugged onto the matching Arduino® UNO R3 connector
pins on the STM32 Nucleo board as shown below.

1.3 System requirements
To use the STM32 Nucleo development boards with the X-NUCLEO-OUT08A1 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-

1.4 Board setup
Step 1. Connect the X-NUCLEO-OUT08A1 to the NUCLEO-F401RE or NUCLEO-G431RB development board
through the Arduino connectors.
Step 2. Connect the X-NUCLEO-OUT08A1 power section (see Section 1.1.2 Power section).
Step 3. Connect the load between CN1 pins 2 and 3.
Step 4. Connect the mini-USB (for NUCLEO-F401RE) or micro-USB (for NUCLEO-G431RB) cable between
your PC and the STM32 Nucleo board.
Step 5. Download the selected firmware (STSW-OUT8F4 for NUCLEO-F401RE or STSW-OUT8G4 for
NUCLEO-G431RB) onto the microcontroller.
Step 6. Provide the digital supply voltage (see Section 1.1.1 Digital section).
Step 7. Reset the example sequence by pushing the black button on the STM32 Nucleo board.

Step 8. Push the blue button on STM32 Nucleo board to choose among the examples provided in the default
firmware package.
Note: When using two boards stacked (e.g. dual channel digital output or single channel safety digital output
application), you have to move some signal enabler resistors from DEFAULT to ALTERNATE position. You can
refer to the expansion board schematic and/or to the table below (where board 0 mounts all the resistors in their
DEFAULT position).
