Product details

Overview

STEVAL-IFP045V1 from STMicroelectronics is an industrial digital output expansion board built around the IPS1025HQ single high-side smart power switch, delivering 2.5 A load current at up to 60 V with 25 mΩ R_ON, galvanic isolation (5 kV), and integrated overload/overtemperature diagnostics. It interfaces directly with STM32 Nucleo boards (NUCLEO-F401RE/NUCLEO-G431RB) via Arduino UNO R3 and Morpho connectors for rapid evaluation of solid-state relay behavior in PLC I/O modules.

For engineers reviewing the STEVAL-IFP045V1 datasheet, STEVAL-IFP045V1 pinout, STEVAL-IFP045V1 application, or STEVAL-IFP045V1 equivalent, this board supports quad-channel stacking, reverse polarity protection, CE/RoHS compliance, and real-time LED status feedback for output state, overload, and thermal faults - critical for industrial control prototyping and digital output module validation.

Technical Context

The board implements a complete isolated digital output stage using optocouplers (ISO1–ISO3) to decouple microcontroller GPIOs from the high-voltage load domain, enabling safe 8–33 V (extendable to 60 V) operation. It leverages the IPS1025HQ's internal charge pump, fast decay circuitry for inductive loads, and smart capacitive load driving logic.

Diagnostic signaling is handled through dedicated FLT1/FLT2 pins routed to red LEDs, while green LED indicates OUT1 state. The board supports both default (J3 closed) and extended voltage modes (J3 open), with supply rail reverse polarity protection via BAT48JFILM diode and transient suppression via SM15T39CA TVS.

Key Specifications

Parameter	Value and Actual Design Meaning
Load current rating	0–2.5 A continuous; supports industrial solenoid, valve, and indicator loads without external heatsinking.
Supply voltage range	8–33 V nominal; extends to 60 V when J3 jumper is open - matches standard 24 V DC industrial rails and higher-voltage legacy systems.
Galvanic isolation	5 kV RMS; achieved via three high-speed optocouplers (ISO1–ISO3), enabling safe MCU-to-load signal separation per IEC 61000-4-5.
Protection features	Undervoltage lock-out, overcurrent shutdown, thermal foldback, and reverse polarity protection - eliminates need for external protection circuitry.
Interface compatibility	Arduino UNO R3 and STM32 Nucleo Morpho pinouts; enables plug-and-play integration with NUCLEO-F401RE and NUCLEO-G431RB without adapter boards.
Stacking capability	Up to four boards can be physically and electrically stacked to evaluate quad-channel digital output modules - validated in reference designs.

FAQ

What microcontroller platforms does STEVAL-IFP045V1 support out of the box?

STEVAL-IFP045V1 natively supports STM32 Nucleo development boards including NUCLEO-F401RE and NUCLEO-G431RB via dual-pin-compatible headers (Arduino UNO R3 and Morpho). No firmware modification or level-shifting is required - GPIO signals are opto-isolated and mapped directly to IN1, FLT1, and FLT2 pins on the IPS1025HQ.

How is galvanic isolation implemented, and what is its rated withstand voltage?

Isolation is implemented using three high-speed 5 kV RMS-rated optocouplers (ISO1–ISO3) placed between MCU GPIOs and the IPS1025HQ control/diagnostic lines. This meets IEC 61000-4-5 surge immunity requirements and enables safe operation in noisy industrial environments with ground potential differences up to ±5 kV.

Can multiple STEVAL-IFP045V1 boards be used together, and how are they synchronized?

Yes - up to four boards can be mechanically stacked and electrically daisy-chained using dedicated header pins. Synchronization is achieved via shared VCC, GND, and isolated control lines; each board operates independently but shares common enable and fault reporting paths, enabling coordinated quad-channel digital output testing.

Does STEVAL-IFP045V1 include software support or drivers?

Yes - ST provides X-CUBE-IPS, a certified STM32Cube expansion package with HAL-based drivers, example projects, and configuration utilities for the IPS1025H family. It supports real-time diagnostics, fault logging, and PWM-controlled output sequencing directly from STM32 firmware.
