STMicroelectronics STEVAL-IFP001V1

Overview

STEVAL-IFP001V1 from STMicroelectronics is an 8-channel high-side driver demonstration board built around the VN808CM-E VIPower M0-3 device, designed for industrial digital output modules in programmable logic controllers. It delivers 8 CMOS-compatible output channels, 1 diagnostic feedback channel, LED status indicators, 4 kV EFT immunity (IEC 61000-4-4), and 2 kV surge protection (IEC 61000-4-5).

For engineers reviewing the STEVAL-IFP001V1 datasheet, STEVAL-IFP001V1 pinout, STEVAL-IFP001V1 application, or STEVAL-IFP001V1 equivalent, this board enables rapid validation of high-side switching behavior, thermal shutdown response, current-limiting accuracy, and EMC robustness in IEC-compliant PLC output stages.

Technical Context

The board implements the full functional interface of the VN808CM-E octal high-side driver, including active current limitation (typ. 1.7 A per channel), thermal shutdown with automatic restart, and diagnostic feedback via open-drain status output. All inputs accept 3.3 V CMOS logic levels and drive grounded loads directly.

EMC hardening includes a SM15T33A unidirectional Transil™ diode for transient suppression, plus layout-level shielding and filtering verified to meet IEC 61000-4-4 (4 kV EFT) and IEC 61000-4-5 (2 kV surge) requirements across industrial temperature ranges.

FAQ

What is the primary function of the STEVAL-IFP001V1 board?

The STEVAL-IFP001V1 is a demonstration board for the VN808CM-E 8-channel high-side driver, enabling engineers to validate load switching, diagnostic feedback, thermal behavior, and EMC immunity in industrial PLC output designs. It is not a production-ready module but a reference implementation with LEDs, terminal blocks, and header interfaces for rapid prototyping.

Does the board support 5 V logic inputs?

No - the board is designed for 3.3 V CMOS-compatible inputs only, matching the VN808CM-E's input threshold specification. Applying 5 V logic may exceed absolute maximum ratings and damage the driver inputs. External level-shifting circuitry is required for 5 V MCU interfacing.

Can the diagnostic feedback channel be used for real-time fault logging?

Yes - the open-drain status output provides aggregated fault indication (e.g., overcurrent or thermal shutdown across any channel). It requires an external pull-up resistor and can be sampled by a microcontroller GPIO to trigger logging, alarm, or safe-state activation in accordance with IEC 61508 SIL-2 requirements.

Is the SM15T33A Transil™ diode replaceable with another TVS device?

Yes - the SM15T33A (33 V standoff, 1500 W peak pulse power) is mounted for transient suppression on the VCC rail. Replacement requires matching voltage rating (±10 %), power rating ≥1500 W, unidirectional polarity, and package compatibility (DO-214AB). ST recommends verifying clamping voltage and response time against IEC 61000-4-5 surge test profiles.
