STMicroelectronics STEVAL-IFP033V1

Overview

STEVAL-IFP033V1 from STMicroelectronics is an evaluation board for the ISO8200BQ galvanically isolated 8-channel high-side driver IC, supporting 0.7 A per channel, 10.5–33 V VCC operation, and 3.3/5 V digital interface; used with STEVAL-PCC009V1/V2 interface boards to validate industrial load switching in PLC I/O modules.

For engineers reviewing the STEVAL-IFP033V1 datasheet, STEVAL-IFP033V1 pinout, STEVAL-IFP033V1 application, or STEVAL-IFP033V1 equivalent, this board enables functional validation of isolated high-side drive timing, fault signaling (open-drain FAULT), synchronous microcontroller control, and thermal overload recovery behavior under real-world load conditions.

Technical Context

The board implements the ISO8200BQ in its native dual-isolated domain configuration: VCC powers the 8-channel power stage (10.5–33 V), while VDD supplies the digital logic (3.3/5 V). It supports direct/synchronous mode communication via IN1–IN8 and SYNC pins, with OUT_EN enabling global output control.

Embedded protection includes per-channel active current limiting, thermal shutdown with automatic restart, loss-of-GND detection, undervoltage lockout with hysteresis, and OR-wired open-drain FAULT signaling for channel overtemperature events - all implemented without external components beyond those shown in the reference schematic.

FAQ

What is the required interface board to operate STEVAL-IFP033V1?

The STEVAL-IFP033V1 must be used with either the STEVAL-PCC009V1 or STEVAL-PCC009V2 interface board to provide microcontroller-level signal translation, power sequencing, and USB-to-serial bridge functionality. These boards generate the synchronous clock (SYNC), enable (OUT_EN), and digital input signals (IN1–IN8) needed to drive the ISO8200BQ.

Does STEVAL-IFP033V1 support both 3.3 V and 5 V logic levels simultaneously?

No - the board's VDD supply must be set to either 3.3 V or 5 V via jumper JP1; it does not support mixed-voltage operation. The selected VDD level determines the logic threshold for IN1–IN8 and SYNC inputs, and must match the host microcontroller's I/O voltage.

How is thermal protection implemented on this evaluation board?

Thermal protection is fully embedded in the ISO8200BQ IC: each channel features independent thermal shutdown with automatic restart. When junction temperature exceeds the trip threshold, the overloaded channel turns off; it resumes operation only after temperature falls below the reset threshold. Non-overloaded channels remain active during recovery.

Can the FAULT pin indicate faults other than overtemperature?

No - the FAULT pin on STEVAL-IFP033V1 is dedicated solely to channel overtemperature (OVT) events, as confirmed by the ISO8200BQ datasheet and schematic. It does not signal undervoltage, loss-of-GND, or short-circuit conditions; those are handled internally with automatic channel disablement but no FAULT assertion.
