STMicroelectronics STEVAL-IFP015V2

Overview

STEVAL-IFP015V2 from STMicroelectronics is a galvanically isolated 8-channel high-side driver demonstration board based on the ISO8200B IC, designed for industrial digital output modules requiring channel-level fault protection, reverse polarity immunity, and IEC 61000-4-2/4/5 compliance. It operates with VCC 10.5–33 V, supports 0.7 A per channel, and interfaces directly with microcontrollers via synchronous mode.

For engineers reviewing the STEVAL-IFP015V2 datasheet, STEVAL-IFP015V2 pinout, STEVAL-IFP015V2 application, or STEVAL-IFP015V2 equivalent, this board enables full evaluation of ISO8200B's galvanic isolation, per-channel thermal shutdown with auto-restart, loss-of-GND detection, undervoltage hysteresis, and OR-wired open-drain FAULT signaling in real-world PLC and factory automation I/O designs.

Technical Context

The board implements the ISO8200B's dual isolated voltage domains: VCC (10.5–33 V) powers the high-side power stage, while VDD (3.3 V or 5 V) supplies the digital interface and logic. All eight outputs are independently protected by active current limiting and thermal shutdown with automatic restart.

It features an open-drain FAULT pin that signals overtemperature or overload on any channel via OR-wired logic, plus loss-of-GND detection that forces all outputs off if analog ground is compromised. Undervoltage lockout includes hysteresis to prevent oscillation during brownout conditions.

FAQ

What interface modes does STEVAL-IFP015V2 support?

The board supports direct/synchronous mode communication with microcontrollers via the ISO8200B's IN1–IN8, SYNC, LOAD, and OUT_EN control lines. It does not implement SPI or I²C; timing is governed by external clock and load strobe signals as defined in the ISO8200B datasheet.

Does STEVAL-IFP015V2 require an external interface board to operate?

Yes - it must be used with either the STEVAL-PCC009V1 or STEVAL-PCC009V2 interface board to provide USB-to-parallel conversion, power regulation, and host PC software control. The board itself contains no USB or serial interface circuitry.

What is the purpose of the large GND area on the PCB?

The extensive ground plane minimizes high-frequency noise coupling between digital and power sections, reduces thermal resistance for the ISO8200B's exposed pad (GND_EP), and enhances EMC performance during IEC 61000-4-4/5 surge testing.

Can STEVAL-IFP015V2 drive AC loads?

No - the ISO8200B is a DC high-side switch only, rated for resistive and inductive DC loads up to 33 V. It lacks zero-crossing detection, TRIAC drive capability, or AC voltage blocking, and is not rated for mains-connected AC operation.
