Smart load management solution for advanced factory automation
New series of ST intelligent power switches (IPS) offer an intuitive smart load management feature to drive any industrial load correctly. The IPS1025H and IPS1025H-32 are designed to meet the requirements of smart load applications for Safety Integrity Level systems thanks to a 60 V operating voltage and embedded protections and diagnostics.
Key features
- 8 to 60V operating voltage
- Very low RDS(on): 25 mΩ (max.)
- Load current limitation:
- 2.5A (min.) IPS1025H
- 5.7A (min.) IPS1025H-32
- Smart driving of capacitive load:
- Programmable initial current threshold (ILIMH) duration using external capacitor
- Fast demagnetization when switching inductive load
- OVL and OVT fault diagnostics and protections
- Case overtemperature protection
- Vcc overvoltage protection

This board provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS1025H single high-side smart power solid state relay, in a digital output module connected to 2.5 A industrial loads.
The X-NUCLEO-OUT05A1 interfaces with the microcontroller on the STM32 Nucleo via 5 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 up to four stacked X-NUCLEO-OUT05A1 expansion boards to evaluate up to four-channel digital output modules.

This software package expands the functionality provided by STM32Cube. It runs on the STM32 microcontroller and includes a driver controlling the IPS1025H or the IPS1025H-32 (single-channel high-side switches for industrial applications) mounted on X-NUCLEO-OUT05A1 or X-NUCLEO-OUT06A1 expansion boards.
This software allows controlling the output channels of the expansion boards when connected to a NUCLEO-F401RE or NUCLEO-G431RB development board.
It is possible to build a system with up to four stacked X-NUCLEO-OUT05A1 and/or X-NUCLEO-OUT06A1 boards to evaluate up to four-channel digital output modules.
This firmware runs on the NUCLEO-F401RE development board and allows the control of the X-NUCLEO-OUT05A1 or X-NUCLEO-OUT06A1 expansion boards using the STSW-IFAPGUI graphical user interface.
The STSW-OUT5F4 contains the software routines to enable USB communication between NUCLEO-F401RE and the system running the GUI, as well as the control of the X-NUCLEO-OUT05A1 or X-NUCLEO-OUT06A1 boards.
The firmware can control a single expansion X-NUCLEO-OUT05A1 or X-NUCLEO-OUT06A1 board.
The STSW-IFAPGUI is based on a common engine and several plug-ins designed to communicate through USB with the application layer running on the NUCLEO-F401RE development board stacked with the expansion board.
