STMicroelectronics STEVAL-IPM10B

Overview

STEVAL-IPM10B from STMicroelectronics is a compact, RoHS-compliant motor drive power evaluation board based on the STGIB10CH60TS-L SLLIMM™ 2nd series intelligent power module. It delivers up to 1200 W nominal power at ≤7 A nominal current, supports 125–400 VDC input, and integrates hardware overcurrent protection, IPM temperature monitoring, Hall/encoder interface, and dual current sensing options (dedicated op-amps or MCU-based) for field-oriented control (FOC) implementation in 3-phase inverter systems.

For engineers reviewing the STEVAL-IPM10B datasheet, STEVAL-IPM10B pinout, STEVAL-IPM10B application, or STEVAL-IPM10B equivalent, this board serves as a validated platform for rapid prototyping of high-efficiency motor drives-particularly when interfacing with STM32-based control boards, evaluating shunt-based current feedback topologies, or validating thermal and fault-protection behavior of SLLIMM™-based inverters.

Technical Context

The board implements a 3-phase IGBT inverter stage using the STGIB10CH60TS-L, which integrates six 600 V/10 A short-circuit rugged IGBTs with built-in bootstrap diodes, undervoltage lockout, smart shutdown logic, NTC temperature sensor, and overcurrent detection circuitry. Its gate driver inputs accept standard 3.3 V logic-level PWM signals (PWM-A-H/L through PWM-C-H/L) and support both single-shunt and three-shunt current sensing configurations.

Signal conditioning includes three TSV994 rail-to-rail op-amps for analog current amplification, configurable biasing (1.65 V reference), and dedicated fault signaling (SD pin, TSO output). The 32-pin motor control connector enables direct mating with ST's STM32 Nucleo or Discovery boards, while onboard test points (e.g., TP23–TP26, TP19) allow real-time probing of phase voltages, current sense outputs, and IPM status signals.

FAQ

What motor types is STEVAL-IPM10B designed to drive?

STEVAL-IPM10B is optimized for permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors rated up to 1200 W and 7 A RMS. Its integrated current sensing, thermal monitoring, and fast fault response make it suitable for field-oriented control (FOC) implementations in compressors, fans, and power tools-verified with ST's X-CUBE-MCSDK firmware stack.

Does STEVAL-IPM10B require an external MCU to operate?

Yes-STEVAL-IPM10B is a power stage only and requires an external controller (e.g., STM32 Nucleo board) to generate PWM signals, process current/voltage feedback, and manage protection logic. It provides all necessary level-shifted gate drive inputs, analog current outputs, and fault status signals compatible with STM32 TIM and ADC peripherals.

Can STEVAL-IPM10B be used with single-shunt current sensing only?

Yes-the board supports both single-shunt and three-shunt topologies via jumper configuration (SW1–SW4). In single-shunt mode, current reconstruction relies on precise timing alignment between PWM edges and ADC sampling, enabled by the board's synchronized trigger outputs and low-latency analog signal path using TSV994 op-amps.

What thermal protection mechanisms are implemented?

The board leverages the STGIB10CH60TS-L's internal NTC thermistor and TSO (Temperature Sense Output) pin to monitor IPM junction temperature. This analog voltage signal is routed to the control board for software-based thermal derating or shutdown. No additional external thermal sensors are required for basic overtemperature protection.
