STMicroelectronics STEVAL-IHM023V3

Overview

STEVAL-IHM023V3 from STMicroelectronics is a fully populated, RoHS-compliant 1 kW three-phase AC-DC inverter evaluation board for induction and PMSM motor control. It integrates the L6390 high- and low-side gate driver and STGP10H60DF 600 V/10 A IGBT in TO-220 package with heatsink, supports 90–285 VAC or 125–400 VDC input, and enables field-oriented control (FOC) via integrated current-sensing op-amps and hardware overcurrent/overtemperature protection.

For engineers reviewing the STEVAL-IHM023V3 datasheet, STEVAL-IHM023V3 pinout, STEVAL-IHM023V3 application, or STEVAL-IHM023V3 equivalent, this board serves as a validated platform for rapid prototyping of sensor-based and sensorless BLDC/PMSM drives, supporting tachometer, Hall/encoder, and BEMF daughterboard interfaces with isolated safety cover and test points.

Technical Context

The board implements a three-phase voltage-source inverter topology using three L6390 drivers - each controlling one half-bridge leg with independent high-side (HV) and low-side (LV) outputs, bootstrap supply, and integrated comparator-based OCP/OTP fault detection. Each channel features dedicated current-sense amplifier inputs and PWM input conditioning logic.

Input power is conditioned via KBU6K bridge rectifier, optional voltage-doubler circuit (65–145 VAC), and VIPer16-based +15 V buck converter. Motor phase outputs (M_phase_A/B/C) are routed to a 34-pin motor connector compatible with STM3210B-EVAL and other ST motor control kits, with regenerative brake control and software/hardware brake enable paths.

FAQ

Does STEVAL-IHM023V3 support sensorless BLDC control?

Yes - it includes dedicated interface pads and routing for a BEMF daughterboard to enable sensorless six-step commutation. The L6390's integrated comparators and configurable blanking time allow reliable back-EMF zero-crossing detection without external components.

What microcontroller boards is STEVAL-IHM023V3 compatible with?

It is natively compatible with the STM3210B-EVAL board via its 34-pin motor control connector and shares signal-level compatibility with other ST motor control kits including STEVAL-IFP01V1 and X-NUCLEO-IHM01A1 through standardized PWM, current sense, and encoder interface definitions.

Can STEVAL-IHM023V3 operate from low-voltage DC sources?

Yes - it supports 18–35 VDC input via the LV-supply jumper (J7), bypassing the AC front-end rectifier and voltage doubler. This mode disables regenerative braking but retains full PWM control, current sensing, and thermal monitoring functionality.

Is isolated communication or debug interface included on the board?

No - STEVAL-IHM023V3 does not integrate isolated UART, SWD, or JTAG interfaces. Debug and control signals (PWM, enable, brake) are routed to headers for connection to external controllers; isolation must be implemented externally per system safety requirements.
