ST X-NUCLEO-OUT15A1 User manual

Introduction
The X-NUCLEO-OUT15A1 is an industrial digital output expansion board for STM32 Nucleo. It provides a powerful and flexible
environment for the evaluation of the driving and diagnostic capabilities of the IPS1025HF single high-side, smart power,
solid-state relay in a digital output module connected to 2.5 A industrial loads.
The X-NUCLEO-OUT15A1 interfaces 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 X-NUCLEO-OUT05A1 stacked on an X-NUCLEO-OUT15A1 expansion board.
Supplying the X-NUCLEO-OUT05A1 through the main supply rail and the X-NUCLEO-OUT15A1 through the output of the
X-NUCLEO-OUT05A1, 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 X-NUCLEO-OUT15A1 output can be
supplied only when both cascaded systems are properly working.

1.1 Overview
The X-NUCLEO-OUT15A1 embeds the IPS1025HF intelligent power switch (IPS), which features overcurrent and
overtemperature protection for safe output load control. The IPS1025HF 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 IPS1025HF 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 over-temperature protection
– PowerSSO 24 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
• Not FCC approved for resale
• RoHS and China RoHS compliant

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-OUT15A1 expansion board.
Figure 2. X-NUCLEO-OUT15A1 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-
OUT15A1 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.

1.1.2 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.

2. Overload red LED
3. IPS1025HF
4. Output channel - green LED
5. Output and power supply connector
For EMC:
• the SM15T39CA transient voltage suppressor (TR1), enabled by closing J3, is placed between VCC and
GND tracks to protect the IPS1025HF 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 IPS1025HF 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.
