STMicroelectronics STEVAL-IFP010V3

Overview

STEVAL-IFP010V3 from STMicroelectronics is a high-side driver demonstration board built around the VNI2140J VIPower IC, designed to drive two independent resistive or inductive loads referenced to ground. It delivers 1 A per channel, features shorted-load and junction/case overtemperature protection, open-load detection in off-state, and 3.3 V CMOS/TTL-compatible inputs with open-drain diagnostic outputs.

For engineers reviewing the STEVAL-IFP010V3 datasheet, STEVAL-IFP010V3 pinout, STEVAL-IFP010V3 application, or STEVAL-IFP010V3 equivalent, this board enables rapid validation of high-side switching for industrial I/O modules, PLC output stages, and 24 V DC control systems requiring thermal independence, fault diagnostics, and IEC 61131-2 compliance.

Technical Context

The board implements dual-channel high-side switching using ST's VIPower M0-7 technology, integrating active current limitation (1 A typ.), undervoltage shutdown (4 V), and non-simultaneous thermal case shutdown restart (TCSD/TCR) to prevent supply peak-current surges during multi-channel overload.

Diagnostic signaling uses open-drain STAT1/STAT2 outputs tied to LED indicators, reporting overtemperature and open-load faults; input logic is 3.3 V compatible with fast demagnetization circuitry for inductive load turn-off.

FAQ

What is the primary function of the STEVAL-IFP010V3?

The STEVAL-IFP010V3 is a demonstration board that implements dual-channel high-side switching using the VNI2140J IC. It enables engineers to evaluate protected 24 V DC load driving with real-time diagnostics, thermal management, and IEC 61131-2 compliance-without designing custom PCBs or adding discrete protection circuitry.

Does the board support inductive load switching with flyback energy handling?

Yes. The VNI2140J on STEVAL-IFP010V3 integrates fast demagnetization circuitry to safely dissipate flyback energy from inductive loads like solenoids and relays. This eliminates the need for external freewheeling diodes while maintaining controlled turn-off timing and voltage clamping.

How are fault conditions reported on this board?

Faults-including overtemperature, open-load (in off-state), and short-to-VCC-are signaled via open-drain STAT1 and STAT2 outputs. These pins drive onboard LEDs (DL1/DL2) and can be directly read by a microcontroller GPIO, enabling immediate system-level response without additional signal conditioning.

Can STEVAL-IFP010V3 be used with 3.3 V microcontrollers?

Yes. Its IN1 and IN2 inputs are fully compatible with 3.3 V CMOS/TTL logic levels, allowing direct connection to common microcontrollers (e.g., STM32, ESP32, PIC32) without level shifters. Input thresholds are specified at 0.8 V (low) and 2.0 V (high), ensuring noise-immune operation in industrial environments.
