STMicroelectronics STEVAL-IFP005V2

Overview

STEVAL-IFP005V2 from STMicroelectronics is a high-side driver demonstration board based on the VN751PT 2.5 A industrial-grade smart power switch, featuring three preconfigured application programs (hand dryer, bathroom fan, multi-entrance room controller), capacitive 5 V ±10% power supply delivering 16 mA average current, and ICC interface for software adjustment.

For engineers reviewing the STEVAL-IFP005V2 datasheet, STEVAL-IFP005V2 pinout, STEVAL-IFP005V2 application, or STEVAL-IFP005V2 equivalent, this board enables rapid validation of VN751PT-based high-side switching in PLCs, IP65/IP67-rated appliances, and industrial load control with thermal protection, short-circuit immunity, and IEC 61131-2 compliance.

Technical Context

This reference design implements robust industrial load switching using the VN751PT high-side driver IC, which integrates 60 mΩ typical R_DS(on), overcurrent/thermal shutdown, and diagnostic feedback. It supports TRIAC-driven AC loads via BTB08-600SW, ACS108, and T1235H-6T switches across three distinct sensor-triggered use cases.

The board uses a capacitive power supply (680 nF EPCOS B32923C3684) delivering 5 V ±10% at 16 mA average output with <0.3 W standby losses at 230 V AC, and includes two potentiometers for sensor sensitivity and TRIAC turn-off delay tuning.

FAQ

What is the primary function of the STEVAL-IFP005V2 board?

The STEVAL-IFP005V2 is a demonstration and development board designed to validate the VN751PT high-side driver IC in real-world industrial load-switching applications. It implements three preconfigured sensor-driven use cases-hand dryer, bathroom fan, and multi-entrance room controller-with hardware-tunable parameters and ICC-based software configuration.

Does the board include overvoltage protection?

No, overvoltage protection is not implemented on the STEVAL-IFP005V2 board. However, dedicated solder pads are provided to add either a varistor across mains input or a Transil diode between TRIAC A2 and gate terminals, enabling user-customized overvoltage clamping per system requirements.

What power supply architecture does the board use?

The board uses a capacitive dropper power supply with a 680 nF EPCOS B32923C3684 capacitor, delivering regulated 5 V ±10% at 16 mA average output current and maintaining <0.3 W standby power loss at 230 V AC input-optimized for compact, low-loss industrial control designs.

Can the board drive AC loads directly?

No-the STEVAL-IFP005V2 does not drive AC loads directly. It controls external TRIACs (BTB08-600SW, ACS108, T1235H-6T) via the VN751PT high-side driver, enabling safe, protected switching of 230 V AC loads such as fans, dryers, and lighting in industrial and building automation systems.
