STMicroelectronics STEVAL-IHM011V1

Overview

STEVAL-IHM011V1 from STMicroelectronics is an obsolete but fully documented evaluation board designed to validate SEMITOP2® IGBT power modules-specifically the 10 A, 600 V STG3P2M10N60B-in three-phase motor control systems. It integrates hardware-based current and thermal protection, BEMF detection, shunt- or IC-based current sensing, and supports 3.3 V/5 V microcontrollers via a 34-pin motor control connector.

For engineers reviewing the STEVAL-IHM011V1 datasheet, STEVAL-IHM011V1 pinout, STEVAL-IHM011V1 application, or STEVAL-IHM011V1 equivalent, this board serves as a reference for IGBT gate drive layout, analog signal conditioning for motor phase currents, hardware fault response timing, and thermal monitoring integration in industrial BLDC/PMSM drives.

Technical Context

The board implements a complete 3-phase inverter stage using the STG3P2M10N60B IGBT module, driven by three L6386D high-voltage gate drivers (each with integrated high-side bootstrap, fault reporting, and 14-pin SOIC package). It features dedicated analog networks for BEMF sensing, current amplification (via TSH24ID and TS374ID op-amps/comparators), and resistive braking.

Hardware protection includes fast overcurrent detection via shunt resistor voltage monitoring (with <1 µs response), thermal shutdown triggered by NTC thermistors (C620 SMD 10 kΩ and 5 Ω types), and bus overvoltage clamping using BZW50 series transzorbs (100 V–120 V breakdown).

FAQ

Is STEVAL-IHM011V1 still in production?

No-STMicroelectronics marked STEVAL-IHM011V1 as obsolete in March 2008 per its revision history. However, Aetrix Electronics maintains legacy inventory and provides full documentation, schematic access, and technical support for continued use in maintenance, reverse engineering, or educational contexts.

What microcontrollers are compatible with this board?

The board supports both 3.3 V and 5 V logic-level microcontrollers via its dedicated 34-pin motor control connector. It has been validated with ST's STM32 and ST7 families, and its PWM buffer inputs (PWM_1HBuf through PWM_3LBuf) accept TTL/CMOS-compatible signals without level shifting.

Can I replace the STG3P2M10N60B module with another IGBT?

Direct replacement requires matching SEMITOP2® mechanical footprint, pinout, and electrical ratings (600 V V_CES, ≥10 A I_C). ST's STG3P2M12N60B (12 A variant) is mechanically identical and electrically compatible; however, thermal and gate drive loop adjustments may be needed due to higher peak current capability.

Does the board include firmware or software support?

No-the STEVAL-IHM011V1 is a hardware-only evaluation platform. It does not include embedded firmware, bootloader, or PC software. Users must provide their own motor control algorithm (e.g., FOC or six-step commutation) running on an external MCU connected via the mc-connector.
