ST X-NUCLEO-OUT09A1 User manual

Introduction
The X-NUCLEO-OUT09A1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible
environment for the evaluation of the driving and diagnostic capabilities of the IPS8160HQ octal high-side smart power solid
state relay, in a digital output module connected to 0.7 A industrial loads.
The X-NUCLEO-OUT09A1 interfaces with the microcontroller on the STM32 Nucleo via 3 kV and 3.7 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 a X-NUCLEO-OUT09A1 stacked on other expansion boards.

1.1 Overview
The X-NUCLEO-OUT09A1 embeds the IPS8160HQ intelligent power switch (IPS), which features overcurrent
and overtemperature protection for safe output loads control.
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 three optocouplers (ISO1,
ISO2, ISO3) for the input signals forward to the device and the status cumulative diagnostic feedback signal of the
device.
The expansion board features:
• Based on the IPS8160HQ octal high-side switch, which features:
– Operating range 10.5 to 36 V
– Low power dissipation (RON(MAX) = 280 mΩ)
– Fast decay for inductive loads
– Undervoltage lock-out
– Overload and overtemperature protections
– Loss of ground protection
– QFN48L 8x6 mm package
• Application board voltage operating range: 15 to 33 V
• Extended voltage operating range (J9 open) up to 36 V
• Operating current: up to 0.7 A per channel
• Green LEDs for outputs on/off status (J12 and J13 close 1-2, 3-4, 5-6, 7-8)
• Red LED for common overheating diagnostic (SW2 close 2-3)
• 3 kV galvanic isolation
• Supply rail reverse polarity protection
• Compatible with STM32 Nucleo development boards
• Equipped with Arduino® UNO R3 connectors
• RoHS and China RoHS compliant
• CE certified

1.2 Digital section
The digital section is associated with the STM32 interface and the digital supply voltage to and from the
X-NUCLEO-OUT09A1 expansion board.
Figure 2. X-NUCLEO-OUT09A1 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino® UNO
R3 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-
OUT09A1 expansion board, in either direction.
Usually, 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 CN11 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 J11 (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.

1.3 Power section
The power section involves the power supply voltage (CN1, pin 1 for VCC, pin 2 for GND), the load connection
(eight loads can be connected between each pin of CN2, CN3, CN4, and CN12 and pin 2 of CN1), EMC
protections (U2), and supply reverse polarity protection (D1).

1. Status (overtemperature) red LED
2. Output channels - green LEDs
3. IPS8160HQ
4. Output and power supply connector
For EMC:
•the SM15T39CA transient voltage suppressor (U2), enabled by closing J9, is placed between VCC and
GND tracks to protect the IPS8160HQ 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 (C11 and C12 - not included) must be
soldered at the predisposed locations;
• the IPS8160HQ 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 performance of the X-NUCLEO-OUT09A1 is 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

1.4 Hardware requirements
The X-NUCLEO-OUT09A1 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-
G431RB STM32 Nucleo development boards.
To function correctly, the X-NUCLEO-OUT09A1 must be plugged onto the matching Arduino® UNO R3 connector
pins on the STM32 Nucleo board as shown below.
Figure 4. X-NUCLEO-OUT09A1 and STM32 Nucleo stack

5Regulatory compliance information
Notice for US Federal Communication Commission (FCC)
For evaluation only; not FCC approved for resale
FCC NOTICE - This kit is designed to allow:
(1) Product developers to evaluate electronic components, circuitry, or software associated with the kit to
determine
whether to incorporate such items in a finished product and
(2) Software developers to write software applications for use with the end product.
This kit is not a finished product and when assembled may not be resold or otherwise marketed unless all
required FCC equipment authorizations are first obtained. Operation is subject to the condition that this product
not cause harmful interference to licensed radio stations and that this product accept harmful interference. Unless
the assembled kit is designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit
must operate under the authority of an FCC license holder or must secure an experimental authorization under
part 5 of this chapter 3.1.2.
Notice for Innovation, Science and Economic Development Canada (ISED)
For evaluation purposes only. This kit generates, uses, and can radiate radio frequency energy and has not been
tested for compliance with the limits of computing devices pursuant to Industry Canada (IC) rules.
À des fins d'évaluation uniquement. Ce kit génère, utilise et peut émettre de l'énergie radiofréquence et n'a pas
été testé pour sa conformité aux limites des appareils informatiques conformément aux règles d'Industrie Canada
(IC).
Notice for the European Union
This device is in conformity with the essential requirements of the Directive 2014/30/EU (EMC) and of the
Directive 2015/863/EU (RoHS).
Notice for the United Kingdom
This device is in compliance with the UK Electromagnetic Compatibility Regulations 2016 (UK S.I. 2016 No. 1091)
