STMicroelectronics STEVAL-IPM05F

Overview

STEVAL-IPM05F from STMicroelectronics is a compact 3-phase motor drive power evaluation board built around the STGIF5CH60TS-L SLLIMM™-2 intelligent power module, delivering up to 500 W at 125–400 VDC input and supporting field-oriented control (FOC) via three-shunt or single-shunt current sensing with dedicated op-amps or MCU-based sensing. It integrates hardware overcurrent protection, NTC-based IPM temperature monitoring, Hall/encoder interface, and a 32-pin motor control connector for STM32 MCU boards.

For engineers reviewing the STEVAL-IPM05F datasheet, STEVAL-IPM05F pinout, STEVAL-IPM05F application, or STEVAL-IPM05F equivalent, this board enables rapid validation of high-efficiency 3-phase inverter topologies in white goods, HVAC compressors, and industrial power tools-focusing on current feedback accuracy, thermal safety, and flexible shunt configuration.

Technical Context

The board implements a gate-driver-integrated 3-phase inverter stage using the STGIF5CH60TS-L IPM, which embeds 600 V, 5 A short-circuit rugged IGBTs with integrated bootstrap diodes, undervoltage lockout, smart shutdown, and TSO (temperature sense output) with NTC biasing. Its analog front-end supports dual current-sensing paths: three independent TSV994 op-amp channels (E1–E3) or external MCU ADC inputs via buffered phase-leg signals (M_phase_A/B/C).

Control interface includes isolated PWM inputs (PWM-A-H/L through PWM-C-H/L), EM_STOP fault latch, SD (shutdown) pin, and Hall/encoder signal conditioning (H1/A+, H2/B+, H3/Z+) with configurable pull-up networks. The 32-pin motor control connector (J3) provides standardized routing for bus voltage, phase outputs, current sense nodes, and auxiliary signals to ST's STM32 motor control development ecosystem.

FAQ

Does STEVAL-IPM05F support both sensorless and sensored FOC?

Yes. The board provides Hall/encoder inputs (H1/H2/H3) for sensored FOC and supports phase-voltage reconstruction via M_phase_A/B/C signals for sensorless observers. Its three-shunt current sensing with <1 µs op-amp latency meets strict timing requirements for real-time current loop execution in STM32-based FOC implementations.

What is the role of the TSO pin on the STGIF5CH60TS-L IPM in this board?

The TSO (Temperature Sense Output) pin delivers a voltage proportional to the IPM die temperature via an internal NTC network. On STEVAL-IPM05F, it connects to U1D (TSV994) for buffering and scaling, enabling direct ADC reading by the host MCU for thermal protection and derating-critical for sustained 500 W operation in enclosed environments.

Can STEVAL-IPM05F be used without an STM32 MCU board?

Yes. The 32-pin J3 connector exposes all critical signals-including PWM inputs, current sense outputs, bus voltage, and fault flags-in breadboard-accessible test points and headers. External controllers can drive the IPM directly using compatible logic-level PWM and enable signals, though STM32 integration provides optimized firmware libraries and motor control examples.

How does the hardware overcurrent protection work on this board?

Hardware overcurrent protection uses comparator-based detection on each shunt resistor (R25/R26/R27). When current exceeds threshold, the comparator triggers the IPM's SD (shutdown) pin within <2 µs, forcing immediate IGBT turn-off. This path operates independently of MCU firmware, ensuring fail-safe response during short-circuit events at the motor terminals.
