Getting started with X-NUCLEO-OUT08A1 industrial digital output expansion board for STM32Nucleo
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.

•
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 (R
ON(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
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.

Overview
1.1.2
The four Arduino ® UNO R3 connectors:
• allow expansion board communication with the peripheral and GPIO resources;
STM32 Nucleo development board accessing STM32
• 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 V
IN
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
G431RB
NUCLEO-
Power section
The power section involves the power supply voltage (CN1, pin 1 V
CC
, pin 2 GND), load connection (between
CN1 pin 3 and CN1 pin 2) and electromagnetic compatibility (EMC) protection (U2).

Hardware requirements
Figure 3. X-NUCLEO-OUT08A1 expansion board: power stage components
1.2
For EMC:
• the transient voltage suppressor (U2), enabled by closing J1, is placed between V
CC
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.
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.

Push the blue button on STM32 Nucleo board to choose among the examples provided in the default firmware package.
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).
